GRBModel.AddGenConstrIndicator()

Add a new general constraint of type GRB.GENCONSTR_INDICATOR to a model.

An INDICATOR constraint $$z = f \rightarrow a^Tx \leq b$$ states that if the binary indicator variable $z$ is equal to $$f \in \{0,1\}$$ , then the linear constraint $$a^Tx \leq b$$ should hold. On the other hand, if $z = 1-f$ , the linear constraint may be violated. The sense of the linear constraint can also be specified to be $=$ or $$\geq$$ .

Note that the indicator variable $z$ of a constraint will be forced to be binary, independent of how it was created.

Multiple signatures are available.

GRBGenConstr	AddGenConstrIndicator (	GRBVar	binvar,
		int	binval,
		GRBLinExpr	expr,
		char	sense,
		double	rhs,
		string	name )

Arguments:

binvar: The binary indicator variable.

binval: The value for the binary indicator variable that would force the linear constraint to be satisfied ( $0$ or $1$ ).

expr: Left-hand side expression for the linear constraint triggered by the indicator.

sense: Sense for the linear constraint. Options are GRB.LESS_EQUAL, GRB.EQUAL, or GRB.GREATER_EQUAL.

rhs: Right-hand side value for the linear constraint.

name: Name for the new general constraint.

Return value:

New general constraint.

GRBGenConstr	AddGenConstrIndicator (	GRBVar	binvar,
		int	binval,
		GRBTempConstr	constr,
		string	name )

Arguments:

binvar: The binary indicator variable.

binval: The value for the binary indicator variable that would force the linear constraint to be satisfied ( $0$ or $1$ ).

constr: Temporary constraint object defining the linear constraint that is triggered by the indicator. The temporary constraint object is created using an overloaded comparison operator. See GRBTempConstr for more information.

name: Name for the new general constraint.

Return value:

New general constraint.
