PSO_Eagle for design problem

The implementation of ES-PSO algorithm for design problem. There are four problems using here.

Eagle strategy (ES) is a two-stage process, developed by Yang et al. ES is inspired by the foraging behavior of eagles. It uses different algorithms which make global search and local search. ES is a two-stage method. Here, Particel Swarm Optimization (PSO) algorithm is improved using ES. This approach were used for some desing problems; welded beam design, tension/compression, pressure vessel, cantilever beam design.
