poj3159 Candies 这题实质为裸的差分约束. 先看最短路模型:若d[v] >= d[u] + w, 则连边u->v,之后就变成了d[v] <= d[u] + w , 即d[v] – d[u] <= w. 再看题目给出的关系:b比a多的糖果数目不超过c个,即d[b] – d[a] <= c ,正好与上面模型一样, 所以连边a->b,最后用dij+heap求最短路就行啦. ps:我用vector一直TLE,后来改用链式前向星才过了orz... #include&…

题目链接:http://acm.hzau.edu.cn/problem.php?id=18 题意是给你两个长度为n的数组,a数组相当于1到n的物品的数量,b数组相当于物品价值,而真正的价值表示是b[i]*k*k(k表示取的数量),给你m表示最少取m个物品.然后让你求取m个的最小的价值和. 一个物品的价值是b[i] , 两个物品的价值是b[i] * 3 + b[i] ... 所以每个物品的价值是b[i] , b[i] * 3 , b[i] * 5 , b[i] * 7 ... 每个物品数量a[i]…

Description 鼹鼠是一种很喜欢挖洞的动物,但每过一定的时间,它还是喜欢把头探出到地面上来透透气的.根据这个特点阿Q编写了一个打鼹鼠的游戏:在一个n*n的网格中,在某些时刻鼹鼠会在某一个网格探出头来透透气.你可以控制一个机器人来打鼹鼠,如果i时刻鼹鼠在某个网格中出现,而机器人也处于同一网格的话,那么这个鼹鼠就会被机器人打死.而机器人每一时刻只能够移动一格或停留在原地不动.机器人的移动是指从当前所处的网格移向相邻的网格,即从坐标为(i,j)的网格移向(i-1, j),(i+1, j),(i…
