addGenConstrOr ( resvar, vars, name="" )

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

An OR constraint states that the binary resultant variable should be if and only if any of the operand variables is equal to . If all operand variables are , then the resultant should be as well.

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

Arguments:

resvar (Var): The variable whose value will be equal to the OR concatenation of the other variables.

vars (list of Var): The variables over which the OR concatenation will be taken.

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

Example usage:

  # x5 = or(x1, x3, x4)
