由于边权都为1故BFS即可(spfa和dijkstra还不太会qwq)反向建边指的是从终点指向起点(即能够到达下标的点)。这样方便记录。(如果正向建边。即记录下标能够到达的点)参考链接AC代码如下: #include <algorithm> #include<iostream> #include<cstdio> #include<cstring> #include<vector> #include<random> #include<...
简介:本周的强化学习我们来到实践部分。我以我在GitHub上开源的项目PiperLiu / Amazing-Brick-DFS-and-DRL为对象,从零开始与各位朋友分享:如何用 python 写一个小游戏、如何匹配传统的深度优先搜索算法来控制、如何匹配传统的广度优先搜索算法来控制、如何匹配深度强化学习算法来控制、强化学习的优势在哪里。无论你是...

//If you know a solution is not far from the root of the tree:BFS, because itisfaster togetcloser node//If the tree is very deep and solutions are rare:BFS, DFS will take a longer time because of the deepth of the tree//If the tree is very wide:DFS,forthe worse cases, both BF...

Dijkstra's algorithm solves the single-source shortest-paths problem in edge-weighted digraphs with nonnegative weights using extra space proportional to V and time proportional to E log V (in the worst case). 2. BFS Find shortest path
