Task Schedule 题意:有N个任务,M台机器.每一个任务给S,P,E分别表示该任务的(最早开始)开始时间,持续时间和(最晚)结束时间:问每一个任务是否能在预定的时间区间内完成: 注:每一个任务一个时间只能由一台机器加工,(意味着可以随意离散加工的时间点,只要所用的时间点之和为P即可;将天数变成点建图)每一台机器一个时间点也只能加工一个任务: 重点是构图:如果将任务抽象成一个点,所需的时间P变成从该点流出的流量(从源点流入边的容量~~)那么只需按照输入顺序标记为点号与源点s连边,边的容量…

题目链接 题意: 有M个机器,N个任务 对第i个任务,需要在[Si,Ei]这段时间内恰有Pi天被process 每天最多有M个机器同时工作 每一天,一个任务若被process,那么它恰占用一个机器. 题解:建图,设一个超级源点S编号为0,超级汇点T编号为1001,编号[1,500]表示任务[1,500],编号[501,100]表示时间[1,500] (为与原题对应,建边时用500作为偏移量). 每一天最多同时加工M个任务,故每一天向超级汇点连一条容量为M的边 以满足此不等关系. 每个任务最多需要…

题目链接:http://acm.hdu.edu.cn/showproblem.php? pid=3572 题意:m台机器.须要做n个任务. 第i个任务.你须要使用机器Pi天,且这个任务要在[Si  ,  Ei]区间内完毕才有效. 对于一个任务,仅仅能由一个机器来完毕.一个机器同一时间仅仅能做一个任务. 当然,一个任务能够分成几段不连续的时间来完毕.问,是否能做完所有任务. 题意非常清晰.也就是推断是否是满流. 对于网络流问题,模板大家都有,关键在于怎样建图(详见资料) 思路:今天问了龙哥,对建图…
