Constructors

	Name	Description
	SimplexSolverMixedIntParams	Constructs a SimplexSolverMixedIntParams object with default values for the parameters. Default values are: PostFeasibilityBranchingStrategy = BranchingStrategies.Automatic; PreFeasibilityBranchingStrategy = BranchingStrategies.Automatic; GapTolerance = 1e-5; GenerateCuts = false; GomoryCutRoundLimit = 200; NodePresolve = false; Presolve = true; SearchStrategy = SearchStrategies.BestBound;

Properties

	Name	Description
	GapTolerance	Gets or sets the tolerance to declare an integer solution optimal. Default is 1e-5
	GenerateCuts	Gets or sets a value that specifies whether to generate cuts. Default is false.
	GomoryCutRoundLimit	Gets or sets the limit on generating cutting planes. Default is 200.
	NodePresolve	Gets or sets a value that indicates whether to perform presolve during a search. Default is false.
	PostFeasibilityBranchingStrategy	Gets or sets the method that the solver uses after feasibility to select variables to branch on. Default is BranchingStrategies.Automatic.
	PreFeasibilityBranchingStrategy	Gets or sets the method that the solver uses before feasibility to select variables to branch on. Default is BranchingStrategies.Automatic.
	Presolve	Gets or sets a value that indicates whether to presolve the mixed integer problem. Default is true.
	SearchStrategy	Gets or sets the search strategy for finding an optimal solution. Default is SearchStrategies.BestBound.
