POJ 1129 Channel Allocation Time Limit: 1000MS   Memory Limit: 10000K Total Submissions: 14191   Accepted: 7229 Description When a radio station is broadcasting over a very large area, repeaters are used to retransmit the signal so that every receive…
题目:http://poj.org/problem?id=1129 题意:求最小m,使平面图能染成m色,相邻两块不同色由四色定理可知顶点最多需要4种颜色即可.我们于是从1开始试到3即可. #include <iostream> #include<cstdio> #include<cstring> #include<cstdlib> #include<stack> #include<queue> #include<iomanip&…
题目: http://poj.org/problem?id=1129 开始没读懂题,看discuss的做法,都是循环枚举的,很麻烦.然后我就决定dfs,调试了半天终于0ms A了. #include <stdio.h> #include <string.h> ][], vis[][]; int n, ans; void calc() { ; ; i < ; i++) { ; j < n; j++) { if(vis[j][i]) { cnt++; break; } }…

题目链接:http://poj.org/problem?id=1129 思路:根据图的四色定理,最多四种颜色就能满足题意,使得相邻的两部分颜色不同.而最多又只有26个点,因此直接dfs即可. #include<iostream> #include<cstdio> #include<cstring> #include<algorithm> using namespace std; ][]; ]; ]; int n,ans; bool Judge(int x,i…
题目:Channel Allocation 题意:要求A:BCD,A与B,C,D都不相同,求不同的值,典型的四色定理: #include <iostream> #include <algorithm> #include <stdlib.h> #include <time.h> #include <cmath> #include <cstdio> #include <string> #include <cstring&…
