My code looks like this: arco(braga, viana_castelo, 5, 55). arco(braga, esposende, 5, 34). arco(braga, povoa_varzim, 5, 55). arco(braga, guimaraes, 5, 25). arco(braga, aveiro, 5, 100). arco(viana_castelo, guimaraes, 10, 81). arco(viana_castelo, esposende, 10, 25). arco(esposende, povoa_varzim, 3, 1…

?- Len = 50, Len =< 45. false. ?- Len = 40, Len =< 45. Len = 40.

[image] EricGT: en = 40, Len =< 45. Does not print the Len =< 45 , just says false, and i want to print the value =< 45

Use gtrace/0 to find out why it is not working: ?- gtrace, caminho_mais_passageiros(A,B). TIP: you are sorting the paths in ascending order and taking the last element after sorting (the last element would be the longest path, not the shortest).

Code doesnt work as intended

Help!
