WebMay 22, 2012 · So Prolog is capable of finding the two paths that lead from a to g and to also tell us there is no other possible paths aside from the two already calculated. We now need to write a function that has a similar design pattern to that of the already used findall and setof predicates. Webx, y = graph_kb.query (pl.Expr ( "path (san_francisco, atlanta, Weight)" ), cut = True, show_path = True ) print (x) [x for x in y if str (x) > "Z" ] # [ {'Weight': 2678}] # ['houston', 'dallas', 'riverside', 'chicago'] Note here the weight is the second shortest path but it can be enhanced by better defining the facts and rules.
