题意:给你n个模块,每个模块在A核花费为ai,在B核跑花费为bi,然后由m个任务(ai,bi,wi),表示如果ai,bi不在同一个核上跑,额外的花费为wi,求最小的花费. 分析: 用最小的费用将对象划分成两个集合的问题,常常可以转化成最小割后解决,这题就是一道经典的问题: 1.考虑把N个模块按照在那个核执行分成两个集合.在A执行为集合S,B为T. 2.当模块属于A集的时候,花费为ai,所以就从向t连一条ai的边,而当模块属于B集的时候,花费为bi,所以就由s连一条向bi的边.然后对于每个任务,当…

Inter Core CPU 型号的尾字母含义: M:表示移动处理器(Mobile Processor):QM:四核移动处理器(Quad Mobile Processor):U:超低电压处理器(Ultra Low Voltage),常用于超级本:XM:至尊移动处理器: 其中U系列为了实现低功耗,性能较差.有些I7的U系列,与I3的M系列性能差不多.…

题意 现在有n个任务,两个机器A和B,每个任务要么在A上完成,要么在B上完成,而且知道每个任务在A和B机器上完成所需要的费用.然后再给m行,每行 a,b,w三个数字.表示如果a任务和b任务不在同一个机器上工作的话,需要额外花费w.现在要求出完成所有任务最小的花费是多少. 思路 上次做的构图题是基于割截断s->t流与题目联系的,而这道题的构图则是基于割把流网络的点划分成了S.T点集,并且不同点集间的边都是割边.这是目前我所接触到的最小割的建模类型. 回到本题构图:源点向任务连一条Ai容量的边,任务…

题目描述:由于越来越多的计算机配置了双核CPU,TinySoft公司的首席技术官员,SetagLilb,决定升级他们的产品-SWODNIW.SWODNIW包含了N个模块,每个模块必须运行在某个CPU中.每个模块在每个CPU中运行的耗费已经被估算出来了,设为Ai和Bi.同时,M对模块之间需要共享数据,如果他们运行在同一个CPU中,共享数据的耗费可以忽略不计,否则,还需要额外的费用.你必须很好地安排这N个模块,使得总耗费最小.思路: 如果将两个CPU分别视为源点和汇点.模块视为顶点,则可以按照以下方…
