WebA* Search. A* Search is an informed best-first search algorithm that efficiently determines the lowest cost path between any two nodes in a directed weighted graph with non-negative edge weights. This algorithm is a variant of Dijkstra’s algorithm. A slight difference arises from the fact that an evaluation function is used to determine which ... WebDec 30, 2012 · This works for undirected graphs with positive edges and arbitrary directed graphs, because in those graphs, any prefix of a shortest path is another shortest path. But shortest paths in undirected graphs with negative edges don't necessarily define trees. Consider the following simple example:
