启发式搜索算法(Heuristic Algorithm)就是用来解决搜索效率问题的,下面将以贪婪最佳优先算法(Greedy Best First Search, GBFS)为例来介绍启发式搜索算法。 GBFS也是图搜索算法的一种,它的算法流程和BFS、DFS并没有本质的不同,区别仍然在于openlist...
for all directed edges from v to w that are in G.adjacentEdges(v) do if vertex w is not labeled as discovered then recursively call DFS(G, w) The order in which theverticesare discovered by this algorithm is called the lexicographic order. A non-recursive implementation of DFS with worst...

DFS (Depth First Search) is an algorithm used to traverse graph or tree. We first select the root node of a tree, or any random node(in case of graph) and explore as far as possible in a branch and then come back to a fixed point. DFS is generally used for connectivity questions....
