题意:在一个叫做QS的星系,他们使用一些特殊的通讯方式,两个人之间通讯需要使用一个网络适配器,但是一个网络适配器只能跟一个人联系,所有它连接几个人就需要及格适配器,而且每个人都有一些不同的偏好,喜欢的适配器的牌子也是不同的,现在让你求出来让QS人之间相互通讯最少需要多少代价? 输入第一行是测试数据组数,下面是一个N,代表N个人,下一样有N个数表示每个人喜欢的适配器的价格,接着一个矩阵,表示两点间通讯(电缆??)的价格. 分析:只要在每条边的权值上加上两个适配器的价格就可以了. *********…

http://acm.zju.edu.cn/onlinejudge/showProblem.do?problemId=586 题目大意: QS是一种生物,要完成通信,需要设备,每个QS需要的设备的价格不同,并且,这种设备只能在两个QS之间用一次,也就是说,如果一个QS需要和3个QS通信的话,它就必须得买3个设备,同时,对方三个也必须买对应的适合自己的设备.同时,每两个QS之间是有距离的,要完成通信还需要网线,给出每两个QS之间的网线的价值.求一棵生成树,使得所需要的费用最少.数据范围:所有数据都…
