A lot of path-finding comes from Dijkstra's original algorithm. There are many variations, such as Floyd Warshall’s algorithm or B*. They share a similar approach by using lists of nodes and distance counts. Various techniques can be mixed to address a variety of situations. The algorithm we’re currently … Näytä lisää

Feb 15, 2021 · The function find_path (graph, v_start, v_end, path_len) checks whether there is a direct or indirect path between two vertices v_start and v_end in graph. We know that there is a direct path between v_start and v_end if both are already neighbors, i.e., graph [v_start] [v_end]==1. def find_path(graph, v_start, v_end, path_len=0):
