A modern Prolog like SWI with CLPFD allows you to apply Prolog's semantics to arithmetic expressions in a way that you never were able to in classic Prolog. Instead of using `is/2`, you use `#=` and some other operators, Prolog can find solutions for expressions that would be very difficult to do in either classic Prolog or any other system. |
