Road accidents during night travel increases day by day and vision impairment due to high beam contributes to the majority of the total fatalities. Headlights of vehicles pose a great danger during night driving. [1] The drivers of most vehicles use high/bright beam while driving at night. This causes a discomfort to the person travelling from the opposite direction. The driver experiences a sudden glare caused due to the high intense headlight beam from the other vehicle coming towards him from the opposite direction. We are expected to dim the headlight to avoid this glare. This glare causes a temporary blindness to a person resulting in road accidents during the night. To avoid such incidents, an embedded prototype of Automatic Headlight adaptor module is proposed. This embedded module automatically switches the high beam to low beam and returns backs to high beam, thus reducing the sudden glare effect. It also eliminates the requirement of manual switching by the driver to switch back to low beam Universal Headlight adaptor module is a unique solution to achieve the above objective, the headlight intensity of the incoming vehicles causing the glare is automatically attenuated to low beam wirelessly by the nearby vehicles affected by high beam. The interconnected modules at every vehicle independently takes the decision on the head light control of the source vehicle causing the glare by evaluating various parameters like vehicle speed, current GPS location, direction of vehicle etc.

While hybridizing the complementary constituent soft computing techniques has displayed improved efficacy, the hybridization of complementary characteristics of different Differential Evolution (DE) variants (could as well be extended to evolutionary algorithms variants in general) through heterogeneous mixing in a distributed framework also holds a great potential. This chapter proposes to mix competitive DE variants with diverse characteristics in a distributed framework as against the typical distributed (homogeneous) Differential Evolution (dDE) algorithms found in DE literature. After an empirical analysis of 14 classical DE variants on 14 test functions, two heterogeneous dDE frameworks dDE_HeM_best and dDE_HeM_worst obtained by mixing best DE variants and worst DE variants, respectively, have been realized, implemented and tested on the benchmark optimization problems. The simulation results have validated the robustness of the heterogeneous mixing of best variants. The chapter also hybridized DE and dynamic DE variants in a distributed framework. The robustness of the resulting framework has been validated by benchmarking it against the state-of-the-art DE algorithms in the literature.

R. Raghu and Dr. Jeyakumar G., “Mathematical Modelling of Migration Process to Measure Population Diversity of Distributed Evolutionary Algorithms”, Indian Journal of Science and Technology, vol. 9, no. 31, 2016.[Abstract]


Background/Objectives: Evolutionary Algorithms (EAs) have a major role in solving optimization problems. Distributed Evolutionary Algorithms (dEAs) improve the performance of classical EAs. In dEAs, the initial population is divided into a number of subpopulations and an independent as well as cooperative coevolution happens among the subpopulations. Methods/Statistical Analysis: The success of dEAs is mainly attributed to the migration process they follow, during the evolution. The migration process alters the diversity of the subpopulations. The contribution of the migration process over the success of dEAs can be better understood and/or improved in the light of changes it brings in the diversity of subpopulations. Three methodologies used in the modelling process are the theoretical approach, statistical approach and the empirical approach. Findings: This paper is to analyze and design a mathematical model of the migration process, for its better understanding. A statistical equation to measure the diversity changes in the subpopulation during the migration process is also derived. The derived equation is validated on different types of populations. Application/Improvement: The derived equation can be applied to study and improve the performance of distributed evolutionary algorithms. More »»

Differential Evolution (DE), the well-known optimization algorithm, is a tool under the roof of Evolutionary Algorithms (EAs) for solving non-linear and non-differential optimization problems. DE has many qualities in its hand, which are attributing to its popularity. DE also is known for its simplicity in solving the given problem with few control parameters: the population size (NP), the mutation rate (F) and the crossover rate (Cr). To avoid the difficulty involved in setting of suitable values for NP, F and Cr many parameter adaptation strategies are proposed in the literature. This paper is to present the working principle of the parameter adaptation strategies of F and Cr. The adaptation strategies are categorized based on the logic used by the authors, and clear insights about all the categories are presented. More »»

M. Sanu and Dr. Jeyakumar G., “Empirical performance analysis of distributed differential evolution for varying migration topologies”, International Journal of Applied Engineering Research, vol. 10, pp. 11919-11932, 2015.[Abstract]


Distributed Differential Evolution, advancement in Differential Evolution (DE) algorithm, is based on the principle of cooperation and co-evolution. It provides multiple search space perspectives, alternate search paths and a more balanced exploitation and exploration capabilities to DE. Altogether it improves solution quality and prevents premature convergence and stagnation to a greater extent, compared to serial DE. The solution quality of Distributed DE is based on the choice of migration parameters. One of the most influencing migration parameter is the topology used. The aim of this work is to empirically analyze the performance of Distributed DE for varying migration topologies. Migration topologies differ from each other on the basis of degree and interconnectivity of nodes. This paper empirically analyzes the performance difference of distributed differential evolution algorithm with varying migration topologies, on a set of benchmarking problems. The migration topologies used in our experiments are basic ring and its variants, star, cartwheel, torus and mesh. Experimental results have shown that no single topology can said to be good for all optimization problems. It depends on the complexity and type of objective function to be optimized. Experimental analyses have also exposed the influence of DE variant, employed in different islands, on the performance ordering of topologies. The influence of other parameters like the selection policy and replacement policy are also found to be crucial. © Research India Publications.

Differential Evolution (DE) is a simple but efficient Evolutionary Algorithm (EA) for stochastic real parameter optimization. With various types of mutation and crossover applicable to DE, there exist many variants of DE. The empirical comparisons between the performances of these variants on chosen benchmarking problems are well reported in literature. However, attempts to analyze the reason for such identified behavior of the variants are scarce. As an attempt in this direction, this paper empirically analyzes the performance as well as the reason for such performance of 14 classical DE variants on 4 benchmarking functions with different modality and decomposability. The empirical analysis is carried out by measuring the mean objective function values (MOV), success rate (Sr), probability of convergence (Pc), quality measure (Qm) and empirical evolution of the variance of the population (Evar). The study also includes reporting evidences for the variants suffering with stagnation and/or premature convergence. © 2014 S. Thangavelu, G. Jeyakumar and C. Shunmuga Velyautham.

Differential Evolution (DE) is a recent addition to the repository of Evolutionary Algorithms (EAs) under Evolutionary Computing Techniques. As similar to other EAs, DE also used for optimization based on population of members. During population optimization the classical DE faces major problem of premature convergence, which causes the sample members to converge early to a local optimum though there is a global optimum in the search space. This paper presents methods to reduce the effect premature convergence and achieve better optimal solutions. There are few works in the literature for same reason by altering the control parameters of DE viz., scaling factor (F) and crossover rate (CR). However, we propose methods to make suitable amendments in the population level directly after detecting premature convergence during the search of DE. These methods can be added as an additional component to DE algorithm. The proposed components are to replace the population members with distinct highest objective function values with random members, to replace the population members with distinct lowest objective function values with random members, to replace members in random fashion and to increase the population size dynamically to counter the early convergence of the population. The above mentioned techniques are implemented and added with classical DE. The performance efficacy of DE with added components is verified on implementing it over a set of Benchmarking Function Suite with functions of different characteristics. The experimental results proved that DE with above components added is able to achieve better optimum values than the classical DE. More »»

Differential Evolution (DE), the real parameter optimization algorithm for population based optimization problem, has proved its superiority over variety benchmarking and real time problems. Measuring and visualizing the changes in the diversity of DE population during its search is one of the ways to understand the algorithmic behavior of DE. This helps to provide better insight for proper tuning of control parameters of DE. Hence, an extensive study to describe various possible ways to measure the population diversity of DE algorithm would be a useful tool for the researchers and practitioners of DE. Towards this research direction, this paper presents variety of population diversity measurement methods available for population based algorithm (in general). As well as, as an initial attempt, three methods out of all the identified methods are implemented for DE/rand/1/bin algorithm for a benchmarking function suite with four different functions. The results recorded are presented and discussed in this paper. More »»

The Distributed Differential Evolution (dDE) algorithm is a natural extension of the Differential Evolution (DE) algorithm, which is a recent addition to the Evolutionary Algorithms (EAs) pool, in the Evolutionary Computing (EC) field of computer science. The algorithmic novelty of the dDE algorithm is well evident in the literature. However, the theoretical studies on the performance of the dDE algorithms are scarcely reported. This paper is an attempt to analyze the performance of the dDE algorithm with a theoretical study. A theoretical equation, to measure the population diversity of the sub-population of the dDE algorithm, after migration, is derived and the validity of the same is verified with a simple distributed framework of dDE with two sub-population.

Conventional code evaluation systems focus on output matching, with little importance being given to evaluating programming style and practice. However, judgement of coding practice is vital to aid the process of learning how to program. We hence propose to define a framework that evaluates source code by judging good coding practice, rather than by matching the output with predetermined test cases. Since the scope of the problem is large, we plan to implement it for a particular programming platform and paradigm. Our proposed approach is to use well established code metrics in order to evaluate training data, which can be fed to a supervised learning framework. The major challenge that we have identified so far is to come up with a definition of parameters that indicates 'good' coding style. We plan to resolve this issue by training our framework to learn to recognize the optimal values and combination of code metrics in order to comprehensively evaluate coding style. © Research India Publications.

This paper proposes a novel distributed differential evolution framework called distributed mixed variants (dynamic) differential evolution ( {Mathematical expression}. This novel framework is a heterogeneous mix of effective differential evolution (DE) and dynamic differential evolution (DDE) variants with diverse characteristics in a distributed framework to result in {Mathematical expression}. The {Mathematical expression}, discussed in this paper, constitute various proportions and combinations of DE/best/2/bin and DDE/best/2/bin as subpopulations with each variant evolving independently but also exchanging information amongst others to co-operatively enhance the efficacy of {Mathematical expression} as whole. The {Mathematical expression} variants have been run on 14 test problems of 30 dimensions to display their competitive performance over the distributed classical and dynamic versions of the constituent variants. The {Mathematical expression}, when benchmarked on a different 13 test problems of 500 as well as 1,000 dimensions, scaled well and outperformed, on an average, five existing distributed differential evolution algorithms.

<p>This paper proposes a novel distributed differential evolution algorithm called Distributed Mixed Variant Differential Evolution (dmvDE). To alleviate the time consuming trial-and-error selection of appropriate Differential Evolution (DE) variant to solve a given optimization problem, dmvDE proposes to mix effective DE variants with diverse characteristics in a distributed framework. The novelty of dmvDEs lies in mixing different DE variants in an island based distributed framework. The 19 dmvDE algorithms, discussed in this paper, constitute various proportions and combinations of four DE variants (DE/rand/1/bin, DE/rand/2/bin, DE/best/2/bin and DE/rand-to-best/1/bin) as subpopulations with each variant evolving independently but also exchanging information amongst others to co-operatively enhance the efficacy of the distributed DE as a whole. The dmvDE algorithms have been run on a set of test problems and compared to the distributed versions of the constituent DE variants. Simulation results show that dmvDEs display a consistent overall improvement in performance than that of distributed DEs. The best of dmvDE algorithms has also been benchmarked against five distributed differential evolution algorithms. Simulation results reiterate the superior performance of the mixing of the DE variants in a distributed frame work. The best of dmvDE algorithms outperforms, on average, all five algorithms considered. © 2013 Springer-Verlag Berlin Heidelberg.</p>

In this paper, we extend the dynamicity of differential evolution (DE) proposed for DE/rand/1/bin and DE/best/1/bin to five more variants DE/rand/2, DE/best/2, DE/current-to-rand/1, DE/current-to-best/1 and DE/rand-to-best/1. We present an empirical, comparative performance, analysis of 14 variants of DE and dynamic differential evolution (DDE) algorithms (7 variants with two crossovers - binomial and exponential) to solve unconstrained global optimization problems. The aim of this paper is to identify competitive DE and DDE variants which perform well on ifferent problems, and to compare the performance of DDE variants with DE variants. The performance of 14 variants of DE and DDE are analyzed by implementing them on 14 test functions. The analysis (done based on mean objective function value, probability of convergence and success performance) shows the superiority of DDE variants and identifies the competitive DE and DDE variants.

Music Therapy is the use of a selected music to obtain the same expected changes and hormonal alterations in the body, played uninterrupted for a while, to obtain the desired positive effect. In this project we try to implement computerized composition of Carnatic Music for curing the ailments. There is a growing awareness that ragas could complement or even be a safe alternative for many medical interventions. For this purpose, it is necessary to design a system which can generate music given the user needs and specifications. Our project aims at implementing this idea by giving the swaras of raagas as input and generating pleasant music using genetic algorithm. This application can be used by the medical practitioners by selecting a raga for playing after giving the patient details and disease as input. Formulating the fitness criteria is a herculean task in order to satisfy coherency, variety, harmony, rhythm and to reduce redundancy. The history of the therapy should also be stored which can be used as a constraint for fitness evaluation. This application is developed using Java. A Java API, called JFugue is used to support music programming. More »»

The learning style of individual students differs from each other. Hence the common way of teaching a course for all the students with same course material, in the existing education system, becoming unsuccessful for the present generation of student community. As a solution to this problem constructing different courseware based on the learning style of the students is an open and challenging research problem. This paper proposes an approach for personalized courseware construction by integrating the Evolutionary Computing (EC) approach with a Data Mining (DM) technique. This proposed approach uses Differential Evolution (DE) algorithm for generating association rules for student learning style models so that relevant materials can be provided for the courseware based on the students‟ requirements and interest. The sample data from FelderSilverman learning style is used for forming rules using DE to extract useful information for courseware recommendation. This paper presents this proposed approach in detail.

A RFID (Radio-Frequency Identification) system consists of RFID readers and tags.RFID technology uses electromagnetic fields to identify the location of the objects attached with the tag and track them continuously. The tags contain electronically stored information about the objects. The most essential requirement for setting up a RFIDenabled system is to deploy (locating and positioning) the RFID readers in order to ensure total coverage of all the RFID tags in an area. Finding an optimal number of readers required and their positions to cover all the tags is an important problem to be solved. Hence, this paper proposes a simple simulation strategy for finding optimal number of RFID readersand their positions for circular coverage using Greedy approach with 100% coverage of tags. The experimental set up and the results are explained in this paper. © 2017 IEEE.

Key frame extraction is a very important task in video analytics. The extracted key frames are used for video summarization and event detection for the given videos. This paper proposes a new algorithmic framework which combines the conventional SSIM (Structural Similarity Index) approach with the state-of-the-art Differential Evolution (DE) algorithm for key frame extraction from video data. The proposed algorithm is implemented to extract key frames from three different videos and its performance is compared with the conventional approach using the average SSIM values. The results show that DE based approach gives comparatively better results when compared to the naive SSIM approach.

The Evolutionary Computing (EC) field of Computer Science has a pool of potential optimization algorithms. They are collectively termed as Evolutionary Algorithms (EAs). The Differential Evolution (DE) algorithm is added recently to this pool. It is known for its simplicity and applicability. DE differs from other EAs by its Differential Mutation logic. There exist many strategies for this mutation logic. This paper proposes a new mutation strategy which employs a self-switching base vector selection mechanism. This self-switching mechanism uses the diversity in the population as a measure to select the base vector either randomly or the best candidate in the population. It is found from the results of the experiments carried out that the proposed mechanism works better on a standard set of benchmarking functions solving unimodal optimization problems.

An in-vehicle fault diagnostics system includes several data logging devices that are distributed across the vehicular network. For an off-board analysis, it is important to know the trigger time of the faults. This paper provides a mechanism to establish a temporal relationship of the logged fault data across the vehicle, thereby enabling offline analysis. To support this, the fault data needs to be timestamped with an accurate system-wide reference time. For the purpose of establishing a global reference time within the vehicular network, the time synchronization mechanism as defined by Automotive Open System Architecture (AUTOSAR) is conceptualized in this paper. A reference implementation of the proposed system is analyzed and validated, where a sample diagnostic event is timestamped with the global time base.

The intent of this paper is to track the height of a tidal wave, using the Kalman filter. By using the Kalman filter algorithm, mathematical expressions are derived to determine the height of a tidal wave. By placing buoy sensors at specific locations in the sea, the real tidal wave height is measured. The buoy sensor is placed at a particular distance from the shore. The sensors continuously record data at that particular position at different time intervals and then transmit the data to the receiver on the shoreline. By continuously evaluating this data, the height of the next wave is being estimated. Since a buoy cannot be placed at every point of the wave, this method provides an easy estimation of replicating the process. These sensors are used to simulate the proposed method of tracking the height of a tidal wave and hence giving a warning in advance in case of a wave height which is more than normal. This warning helps people living in coastal areas to vacate the place in advance, therefore avoiding fatality. This tracking of the tidal wave height is useful particularly in the case of a tsunami. By adding Gaussian white noise to the input data from the buoy sensors, a prediction of the next wave height is possible. © 2016 IEEE.

In this paper we present an empirical, comparative performance, analysis of fourteen variants of Differential Evolution (DE) and Dynamic Differential Evolution (DDE) algorithms to solve unconstrained global optimization problems. The aim is to compare DDE, which employs a dynamic evolution mechanism, against DE and to identify the competitive variants which perform reasonably well on problems with different features. The fourteen variants of DE and DDE are benchmarked on 6 test functions grouped by features - unimodal separable, unimodal nonseparable, multimodal separable and multimodal non-separable. The analysis identifies the competitive variants and shows that DDE variants consistently outperform their classical counter parts. More »»

IEEE, Adiparasakthi College of Engineering, 2017.[Abstract]


A RFID (Radio-Frequency Identification) system comprises of an arrangement of RFID readers and RFID tags. A RFID system is known for its quick identification of objects to which the RFID tags are attached. RFID system has been used mainly in industries for identifying and tracking important assets. The most essential property of a RFID system is deploying RFID readers to ensure total coverage of all the RFID tags in an area. The total cost of an RFID system relies mostly on the number of readers. Thus, finding an optimal number of readers and their positions to cover all tags is a standout amongst the most vital issues in a RFID system. This paper proposes a simple simulation strategy for optimal RFID reader placement for a system with RFID readers of circular coverage. This simulation is carried with Differential Evolution (DE) algorithm, which has achieved 100% coverage with optimal number of RFID readers. The experimental set up and the results are explained in this paper.

Nambiar and Dr. Jeyakumar G., “Co-operative Co-evolution Based Hybridization of Differential Evolution and Particle Swarm Optimization Algorithms in Distributed Environment”, Emerging Research in Computing, Information, Communication and Applications: ERCICA 2015, vol. 2. Springer India, New Delhi, pp. 175–187, 2015.[Abstract]


Evolutionary computing algorithms play a great role in solving real time optimization problems. One of the evolutionary computing algorithm is Particle Swarm Optimization algorithm (PSO). The aim of this paper is to propose a model to improve the performance of PSO algorithm. Hybrid models of Particle Swarm Optimization (PSO) algorithm and Differential Evolution (DE) has already proved to be one of the better approaches for solving real world complex, dynamic and multimodal optimization problems. But these models hybridize PSO and DE to form a new serial algorithm. In these serial hybridization models, we are losing the originality of both DE and PSO algorithms since the structure of both the algorithms is being modified to get the hybridized PSO and DE algorithm. In this paper, we develop a model for PSO in distributed environment with improved performance in terms of speed and accuracy. The proposed model is a hybridized distributed mixing of DE and PSO (dm-DEPSO) which improves the performance of PSO algorithm. In this model, algorithms are implemented in a cluster environment to perform co-operative co-evolution. Better solutions are migrated from one node to another in the cluster environment. Co-operative co-evolving model shows better performance in terms of speed and accuracy. The algorithm is applied to a set of eight benchmarking functions and their performance are compared by mean of objective function values, standard deviation of objective function values, success rate, probability of convergence and quality measure.

In this paper we derive an analytical expression to describe the evolution of expected population variance for Differential Evolution (DE) variant—DE/current-to-best/1/bin (as a measure of its explorative power). The derived theoretical evolution of population variance has been validated by comparing it against the empirical evolution of population variance by DE/current-to-best/1/bin on four benchmark functions.

Music speaks what cannot be expressed, soothes the mind and gives it rest, heals the heart and makes is whole. Not everyone is gifted with a good voice but almost everyone has good ears when it comes to pleasant music.This music ranges from strictly organized compositions, through improvisational music to aleatoric forms which makes it tough to automate music generation. In this paper we try to bring in the idea of automated Carnatic music generation using genetic algorithm and its applications. Firstly a variety of compositions on specific ragas can be generated which can be improvised to deliver a good quality musical concert. This concept of automated music generation can also be applied to build an ‘online musical instrument tutorials’ by which users get to learn any instrument level by level. The work can also be modified to produce music of same fitness as any pre existing composition by giving the latter’s notes as input. The application of computerized composition can be used in Music Therapy which is the use of a selected music to obtain the same expected changes and hormonal alterations in the body,played uninterrupted for a while, to obtain the desired positive effect. The above mentioned field of music generation can be used by the medical practitioners by selecting a raga for playing after giving the patient details and disease as input. The application is developed using Java. A Java API, called JFugue is used to support music programming. More »»
