Detailed Description

Differential Evolution configuration object.

The algorithm and strategy names are taken from here:

Price, K., Storn, R., 1997. Differential Evolution - A Simple and Efficient Heuristic for Global Optimization over Continuous Spaces. Journal of Global Optimization, Kluwer Academic Publishers, 1997, Vol. 11, pp. 341 - 359.

There are seven basic strategies for creating mutant population currently implemented. Three basic crossover types are also available.

Future development: 1) base element type to be extracted 2) L differences to be used instead of fixed number 3) various weights distributions for the differences (dither etc.) 4) printFullInfo parameter usage to track the algorithm


This was reported to fail tests on Mac OS X 10.8.4.
