Dear All, Was trying:
GNU Prolog 1.4.5 (64 bits) Copyright (C) 1999-2018 Daniel Diaz fib(0, R) :- !, R = 0. fib(1, R) :- !, R = 1. fib(N, X) :- M is N-1, fib(M, Y), K is M-1, fib(K, Z), X is Y+Z. ?- fib(30, X). But it crashed. Is this to expect? Best Regards _______________________________________________ Bug-prolog mailing list Bug-prolog@gnu.org https://lists.gnu.org/mailman/listinfo/bug-prolog
