Add a new general constraint of type GRB.GENCONSTR_AND to a model.
An AND constraint states that the binary resultant variable should be if and only if all of the operand variables are equal to . If any of the operand variables is , 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.
resvar: The resultant variable of the new constraint.
vars: Array of variables that are the operands of the new constraint.
name: Name for the new general constraint.
New general constraint.
