Hi Please ... what is my mistake in this trivial example with sets: %%:-lib(ic). %%:-lib(branch_and_bound). :-lib(fd). :-lib(fd_sets). %% data veloc(1,[61,66,63,69]). veloc(4,[12,122,18,1,9,7]). go :- veloc(1,L1), model(L1), veloc(4,L4), model(L4). model(L) :- length(L,N), writeln( n: N), writeln( l: L), sort(L, Dominio), writeln( dom: Dominio), find_2_others(N, N1, N2), writeln( n1: N1) , writeln( n2: N2) , write('xxxxxxxx is it correct this definition?'), L1 :: [ ] .. Dominio, L2 :: [ ] .. Dominio, L3 :: [ ] .. Dominio, #(L1, N1), #(L2, N2), #(L3, N), union(L1, L2, L3), label_sets([L1, L2]). The error is: undefined arithmetic expression in _472 is [] in module fd_domain -- claudio ( )) |""|-. |__|-' ********************************************************************** Skype: claudio_cesar_sa http://claudiocesar.wordpress.com/about/ ***********************************************************************Received on Sat Dec 03 2011 - 08:26:34 CET
