[Poj2349]Arctic Network Description 国防部(DND)要用无线网络连接北部几个哨所.两种不同的通信技术被用于建立网络:每一个哨所有一个无线电收发器,一些哨所将有一个卫星频道. 任何两个有卫星信道的哨所可以通过卫星进行通信,而不管他们的位置.同时,当两个哨所之间的距离不超过D时可以通过无线电通讯,D取决于对收发器的功率.功率越大,D也越大,但成本更高.出于采购和维修的方便,所有哨所的收发器必须是相同的:那就是说,D值对每一个哨所相同. 你的任务是确定收发器的D的最…

[题意] 南极有n个科研站, 要把这些站用卫星或者无线电连接起来,使得任意两个都能直接或者间接相连.任意两个都有安装卫星设备的,都可以直接通过卫星通信,不管它们距离有多远. 而安装有无线电设备的两个站,距离不能超过D. D越长费用越多. 现在有s个卫星设备可以安装,还有足够多的无线电设备,求一个方案,使得费用D最少(D取决与所有用无线电通信的花费最大的那条路径). InputThe first line of input contains N, the number of test cases.…

题目 /*********题意解说——来自discuss——by sixshine**************/ 有卫星电台的城市之间可以任意联络.没有卫星电台的城市只能和距离小于等于D的城市联络.题目告诉你卫星电台的个数S,让你求最小的D. 做最小生成树,去掉最长的S条边后,剩下最长的边就是D. 也就是求最小生成树中第S+1长的边. 完毕. /********************************************************/ //听说听木看懂之后,数据很水,果然…
