|  | ## Description
 | |||
|  | <section id="description">以下无向网络由七个顶点和十二个边组成,总权重为243。 <p>相同的网络可以由下面的矩阵表示。 ABCDEFG A-161221 --- B16--1720-- C12--28-31- D211728-181923 E-20-18--11 F-3119--27 G --- 231127-但是,有可能通过删除一些边缘来优化网络,并仍然确保网络上的所有点保持连接。实现最大节省的网络如下所示。它的权重为93,比原始网络节省了243  -  93 = 150。 </p><p>使用network.txt(右键单击并“保存链接/目标为...”),一个6K文本文件包含一个具有四十个顶点的网络,并以矩阵形式给出,找到通过删除冗余边缘可以实现的最大节省确保网络保持连接。 </p></section> | |||
