GRBModel::addGenConstrOr()

Add a new general constraint of type GRB_GENCONSTR_OR to a model.

An OR constraint $$r = \mbox{or}\{x_1,\ldots,x_n\}$$ states that the binary resultant variable $r$ should be $1$ if and only if any of the operand variables $$x_1,\ldots,x_n$$ is equal to . If all operand variables are $0$ , then the resultant should be as well.

Note that all variables participating in such a constraint will be forced to be binary, independent of how they were created.

GRBGenConstr	addGenConstrOr (	GRBVar	resvar,
		const GRBVar*	vars,
		int	len,
		string	name="" )

Arguments:

resvar: The resultant binary variable of the new constraint.

vars: Array of binary variables that are the operands of the new constraint.

len: Number of operands in the new constraint (length of vars array).

name (optional): Name for the new general constraint.

Return value:

New general constraint.
