Last change on this file since 7025 was 7025, checked in by sforsten, 11 years ago

#1669: benchmark problems of Nguyen, Korns and Keijzer from http://groups.csail.mit.edu/EVO-DesignOpt/GPBenchmarks/ have been added. The benchmark problems from http://www.vanillamodeling.com/ have been adapted to the ones from Vladislavleva.

Not all benchmarks are working correctly so far, but they will be tested soon.
