getdefaultparams.m

This contribution provides functions for finding an optimum parameter set using the evolutionary alg

function DEParamsDefault = getdefaultparams
%GETDEFAULTPARAMS  Get default parameters for differential evolution.
%		DEParams = GETDEFAULTPARAMS returns a structure with a set of default
%		parameters for differential evolution.
