• Changed Coordinates to OptionalValueParameter so that distance matrix-only instances can be executed (but not visualized).
• Updated VNS-OP sample.

Location:

branches/HeuristicLab.Problems.Orienteering

Files:

• HeuristicLab.Optimizer/3.3/Documents/VNS_OP.hl (modified) (previous)
• HeuristicLab.Problems.Orienteering/3.3/OrienteeringProblem.cs (modified) (3 diffs)
