Particle evolutionary swarm optimization with linearly decreasing ε-tolerance

Abstract

We introduce the PESO (Particle Evolutionary Swarm Optimization) algorithm for solving single objective constrained optimization problems. PESO algorithm, proposes two perturbation operators: "c-perturbation" and "m-perturbation", The goal of these operators is to prevent premature convergence and the poor diversity issues observed in Particle Swarm Optimization (PSO) implementations. Constraint handling is based on simple feasibility rules, enhanced with a dynamic e-tolerance approach applicable to equality constraints. PESO is compared and outperforms highly competitive algorithms representative of the state of the art. © Springer-Verlag Berlin Heidelberg 2005.
