Parameter | Type | Comment |
---|---|---|
General.MPP | Boolean |
Minimal Perturbation Problem |
Value.MPPLimit | Integer |
Limit on the number of perturbations (only in case of MPP, i.e., when General.MPP=true). MPP limit is decreased when a complete solution is found. If set to -1, it is no used |
Value.InitialSelectionProb | Double |
Probability of selection of initial value (only in case of MPP) |
Value.WeightDeltaInitialAssignments | Double |
Weight of difference in the number of assignments of initial values in case of selection of the value(only in case of MPP) |
Value.RandomWalkProb | Double |
Probability of random selection of a good value |
Value.WeightNrAssignments | Double |
Weight of the number of previous assignments of the value |
Value.WeightValue | Double |
Weight of the value itself (e.g., for minCSP) |
