Improved Chaotic Particle Swarm Optimization Algorithm with More Symmetric Distribution for Numerical Function Optimization

Abstract: As a global-optimized and naturally inspired algorithm, particle swarm optimization (PSO) is characterized by its high quality and easy application in practical optimization problems. However, PSO has some obvious drawbacks, such as early convergence and slow convergence speed. Therefore, we introduced some appropriate improvements to PSO and proposed a novel chaotic PSO variant with arctangent acceleration coefficient (CPSO-AT). A total of 10 numerical optimization functions were employed to test the performa… Show more

“…Another promising research area is chaos theory in evolutionary optimization. The initial locations of agents in swarm intelligence algorithms affect the quality of the obtained solution, so a chaos-based pseudorandom number generator could be used to initialize the population in an evolutionary-inspired algorithm [50].…”

“…Fan and Jen attempted to develop the basic PSO effectiveness and convergence by adopting the thought of multiple cooperative swarms, and then, an enhanced partial search PSO (EPS-PSO) [29] was proposed. Ma et al proposed the chaotic PSO-arctangent acceleration coefficient algorithm (CPSO-AT) [30], which strengthened the effectiveness of the original PSO through chaotic initialization and nonlinear optimization. Zhang et al proposed a cooperative coevolutionary bare-bones particle swarm optimization (CCBBPSO) with function independent decomposition (FID), called CCBBPSO-FID [31].…”

“…Finding a balance between the two, i.e., global search and local search, is a challenging task. Ma [19] proposed a chaotic PSO algorithm with arctangent acceleration coefficient to seek a balance between global search and local search. Wang [20] proposed a hybrid quantum PSO algorithm, which uses flight and jump operations to improve the accuracy of QPSO (Quantum Particle Swarm Optimization) and enhance the search ability.…”
