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.

WebApr 16, 2024 · Prolog's default search algorithm is depth-first search (DFS), which is sometimes not convenient: DFS doesn't always find the solution for all problems, and when it does, it might not find the optimal solution. Let's say we want to find the shortest path through a directed graph with nodes represented by symbols and arc by the predicate arc/2. Web1 day ago · The problem is that I'm pretty sure that there is a path between these two nodes.

WebFeb 21, 2024 · The solid/black line indicates the shortest path, the dashed/red line indicates the next path by length, which however is very similar to the shortest path, and the dotted/blue line indicates a path that is clearly longer, but significantly different from the shortest path as it passes through a very distant part of the city’s road network. WebThe aim was to have a Prolog implementation that can inform a potential user on how to get from a station to any other station on the network. It would also compute the shortest path between any two stations in terms of distance, the shortest path between any two stations in terms of time and the number of changes required between any two stations.
