An Improved PSO Method With Application to Multimodal Functions of Inverse Problems

Abstract

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> Improvements that use new formulas and strategies for updating the particles' velocity and position, craziness, adaptive velocity adjustment scheme, and the use of a simple refinement searching scheme and so on are proposed on particle swarm optimization (PSO) methods to enhance their performances. Numerical results are given to validate the feasibility and to demonstrate the merits of the proposed method. </para>
