Properties
  NameDescription
Public propertyGapTolerance
Gets or sets the tolerance to declare an integer solution optimal. Default is 1e-5
Public propertyGenerateCuts
Gets or sets a value that specifies whether to generate cuts. Default is false.
Public propertyGomoryCutRoundLimit
Gets or sets the limit on generating cutting planes. Default is 200.
Public propertyNodePresolve
Gets or sets a value that indicates whether to perform presolve during a search. Default is false.
Public propertyPostFeasibilityBranchingStrategy
Gets or sets the method that the solver uses after feasibility to select variables to branch on. Default is BranchingStrategies.Automatic.
Public propertyPreFeasibilityBranchingStrategy
Gets or sets the method that the solver uses before feasibility to select variables to branch on. Default is BranchingStrategies.Automatic.
Public propertyPresolve
Gets or sets a value that indicates whether to presolve the mixed integer problem. Default is true.
Public propertySearchStrategy
Gets or sets the search strategy for finding an optimal solution. Default is SearchStrategies.BestBound.
