(* basically, we have two sets, one for red node and the other for black node*) (* we keep marking color to nodes via DFS and different level of nodes go to coresponding color set*) (* unless a node is meant to be one color but already in the set of the other color*) ...
显然BFS和DFS在搜索的时候,并没有利用终点在哪里这个信息而去选择某些离终点近的node去优先visit。BFS和DFS只按部就班,一个是FIFO,一个LIFO,所以导致到达终点的速度大部分时候不是很快。于是就有了贪婪的Best First Search(It's a greedy algorithm: agreedyalgorithm is one that chooses the best-looking option...

理解BFS以及DFS主要就是程序中的几个要点。记住了就好。 二、广度优先搜索(BFS) 2.1 、通过词梯问题,了解BFS。 词梯问题:。比如,将单词“ FOOL”转变成单词“ SAGE”。在词梯问题中,你必须以一次只改变一个字母的方式来逐步转变单词。每一步你都必须将一个单词转变成另一个单词,并且不允许转变成一个不存在的单...
