Changeset 8016 for trunk/sources/HeuristicLab.Algorithms.SimulatedAnnealing/3.3/SimulatedAnnealingMainLoop.cs

#1828:

• Added a SingleValueAnalyzer to HeuristicLab.Analysis
  • The ValueAnalyzer was not usable without changing the operator graph, it has a ScopeTreeLookupParameter and is only suitable to analyze values of children
  • I think we need an analyzer like this anyway so I implemented it and named it SingleValueAnalyzer
• Added that to SA and parameterized accordingly
