Comparisons of Genetic Algorithm and Particle Swarm Optimization

Genetic algorithm （GA） and particle swarm Department of Electronics and Communication Engineering, Sun Yat-sen University, Guangzhou 510006, China 2. Guangdong Key Laboratory of Health Informatics, optimization （PSO） have been broadly used in many fields, such as function optimization, production scheduling, machine learning and data mining, etc. This paper makes com- prehensive and systematic comparisons of GA and PSO on dealing with a series of benchmark problems, analyzes their performance on solving unimodal and multimodal functions, and further tests the robustness of two algorithms for investigating the influences of parameters to the performance of the algorithms. This paper finally concludes the characteristics of the two algorithms and discusses their improvement strategies. The goal of this paper is to provide technical guidance for the selection of algorithms in engineering applications.
