WebOperators in Prolog notation contains a number of arguments in parenthesis like likes (hary, jack). Any user-defined predicate which has two arguments can be converted into an infix operator as an alternative. In this, we can write the functor between the two arguments, and they have no parenthesis like hary likes jack WebNov 27, 2024 · To control the way Prolog evaluates your program, you can use the cut operator: !. the cut operator is an atom, and can be used in the following way: a(X) :- b(X), c(X), !, d(X). If Prolog finds a cut in a rule, it will not backtrack on the choices it has made.
