Performance simulation of Hybrid Particle Swarm Optimization for MATLAB
ABSTRACT
Real life optimization problems are often so complex that finding the best solution becomes computationally infeasible. Therefore, an intelligent approach is to search for a good approximate solution consuming lesser computational resources. Several engineering problems contain multiple objectives that need to be addressed simultaneously. Many techniques have been proposed that imitate nature’s own ingenious ways to explore optimal solutions for both single and multi-objective
optimization problems. Earliest of the nature inspired techniques are genetic and other evolutionary heuristics that evoke Darwinian evolution principles.

This dissertation presents the persity instance study of swarm intelligence through discussing a typical realization mode-particle swarm optimization(PSO).he systematical study on optimization efficiency evaluation of swarm intelligence is addressed firstly.Based on the basal evaluation index system in the field of intelligent optimization,a kind of evaluation model used to evaluate synthetically the general optimization performance and population dynamics of particle swarm optimization is proposed.This evaluation model including optimum value dynamics,population aggregation dynamics,population persity dynamics,as well as convergence dynamics of population center is simulated and validated by function optimization problems.
Keywords:
