This contribution provides functions for finding an optimum parameter set using the evolutionary algorithm of Differential Evolution. Simply speaking: If you have some complicated function of which you are unable to compute a derivative, and you want to find the parameter set minimizing the output of the function, using this package is one possible way to go. -This contribution provides functions for finding an optimum parameter set using the evolutionary algorithm of Differential Evolution.
