Pathfinding or pathing is the plotting, by a computer application, of the shortest route between two points. It is a more practical variant on solving mazes. This field of research is based heavily on Dijkstra's algorithm for finding the shortest path on a weighted graph. Pathfinding is closely related to the shortest path problem, within graph theory, … WebMay 16, 2016 · To find the maximum cost from S to T: Topologically sort the nodes of the graph as S = x_0, x_1, ..., x_n = T. (Ignore any nodes that can reach S or be reached from T.) The maximum cost from S to S is the weight of S. Assuming you've computed the maximum cost from S to x_i for all i < k, the maximum cost from S to x_k is the cost of … WebSep 28, 2024 · Dijkstra's Algorithm can only work with graphs that have positive weights.
