Changeset 10850 for branches/SimSharp/HeuristicLab.Problems.Programmable/3.3/Datastructures/ParameterVector.cs

Timestamp:

05/14/14 14:46:00 (10 years ago)

Author:

Message:

#2174: Major refactoring:

• ParameterVector is only a temporary datastructure that is constructed for evaluation purposes only
• Multiple permutations are allowed
• Special support for single-vector encodings (to apply specialized algorithms such as PSO or CMA-ES)
• General support for multi-vector encoding

Location:

Files:

• . (added)
• ParameterVector.cs (copied) (copied from branches/SimSharp/HeuristicLab.Encodings.ParameterVector/ParameterVector.cs) (1 diff)
