神题,搜索太差,来自网络的题解与程序 思路: 封锁出口或者入口周围的格子. 最多需要4个封锁点. 所以我们可以采取这样的策略: 1.寻找一条盗贼的可行路线,如果没有,返回0. 2.计算封锁出口和入口四周需要的封锁点数量,取小的一个,假设是k,k <=4 3.从少到多,遍历所有封锁点个数小于k的方案,验证是否是一条有效的覆盖方案 (可以通过是否阻止了1中的盗贼线路进行快速验证). 如果有有效覆盖方案,返回这个方案的覆盖点值,否则继续. 4.如果没有比k小的覆盖方案,返回k. 时间复杂度: 最多(M…

http://acm.hdu.edu.cn/showproblem.php?pid=1983 首先,题目要求出口和入口不能封闭,那么,只要把出口或入口的周围全给封闭了那盗贼肯定无法成功偷盗,出口或入口周围最多 会有四个点,所以初始答案ans=4(没必要计算出出口或入口可以封闭的最小值,就初始为4就好),然后从一到四枚举看有没有 最小的符合条件的值, 所以先用BFS查找出至少偷到一个宝石的最小时间的路径,记录下来,然后枚举封闭路径上的点递归回去,再BFS判断是否能偷盗 成功---DFS中插入BFS…
