When I use a findall it goes into an infinite loop. assertarv([N|R]):- assert(veiculos_troncos(N)), assertarv(R). assertarv([]). When I use findall(A,veiculos_troncos(A),NTr) , after having used the above predicate to assert many points (coordenates). This is what I get(using findall): Exit: (22) veiculos_troncos((-7, 6)) ? creep Redo: (22) veiculos_troncos(_G6719) ? creep Exit: (22) veiculos_troncos((-6, 6)) ? creep Redo: (22) veiculos_troncos(_G6719) ? creep Exit: (22) veiculos_troncos((-4, 4)) ?

A generic definition is thus called for. Note that the notions defined in graph theory do not readily match what is commonly expected. Most notably, we are not interested in the edges' names. Worse, also graph theory has changed a bit, introducing the notion of walk , noting Traditionally, a path referred to what is now usually known as an open walk. Nowadays, when stated without any
