easy的模拟,需要加上alpha-beta剪枝,以及一个很神的剪枝。那就是初始局面小于等于4个棋子的时候,一定没有必胜手,这个很容易想到。 注意Min Max里ok判断的是上一步,所以inf和-inf要区分开。 1#include <algorithm>2#include <iostream>3#include <iomanip>4#include <cstring>5#include <climits>6#include <co...
神题,我是以前花了一周时间才写出minmax,有经验所以补上alpha-beta就会容易一些。(虽然alpha-beta剪枝也很难) 所以题解就不写了,想学minmax的话网上有很多现成的。
