Last change on this file since 6121 was 6121, checked in by jhelm, 13 years ago

#1329: Implemented basic functionalities of problemdefinition, encodings and primitive operators. A GA can already be applied on the problem to compute a solution it seems however that the current implementation isn't very efficient so the process takes some time.
