AND Constraints
This constraint handler deals with AND-constraints. These are constraint of the form: \[ r = x_1 \wedge x_2 \wedge \dots \wedge x_n \] where \(x_i\) is a binary variable for all \(i\). Hence, \(r\) is also of binary type. The variable \(r\) is called resultant and the \(x\)'s operators.
