In this paper, firstly, not only the incidence matrix ,adjacent matrix, cycle matrix, cut-set matrix of an undirected graph are summarized, but also the close contact between a graph and its corresponding matrix are discussed ; secondly, many problems of a graph which are solved by analysing its matrix are listed as follows:1、The co-tree set of a graph is obtained by using its cycle-matrix ; 2欧美男女a片、The branches of its spanning tree are given by using its cut-set matrix ; 3、By making use of the incidence matrix of a graph ,not only its vertex cut 国产三级伦视频、cut vertex 美女裸体无遮挡久久久精品、isolated point and spanning tree can be obtained ,but also the two sides which are whether parallel or not can be judged ;4、By using their adjacent matrix ,the two graphes which are whether isomorphous or not can be judged; once more, there is a detailed introduction in view of special graph (for example: bigaritite graph ,regular graph and so on);last but not least, a graph method of calculating the N power of a matrix is given and the practical applications of the theorem for degree is indicated.

本文首先綜述了無向圖的關(guān)聯(lián)矩陣加勒比无码HEZYO，鄰接矩陣www.偷，圈矩陣，割集矩陣以及圖和它對(duì)應(yīng)矩陣之間的關(guān)系亚洲色图欧美日韩；其次總結(jié)出了利用上述各類矩陣可以解決的圖的若干問題：1欧美中文自拍另类、利用圖的圈矩陣可以求其連枝集；2先锋影音网址、利用圖的割集矩陣可以求其生成樹的樹枝美女被艹69；3、利用圖的關(guān)聯(lián)矩陣不僅可以求其割點(diǎn)毛片全部免费播效、點(diǎn)割集国产AV妓女影院、連通度、孤立點(diǎn)和生成樹91干干，而且可以判斷兩條邊是否平行欧美性XXXX69；4、利用圖的鄰接矩陣可以判斷兩個(gè)圖是否同構(gòu)欧美69；再次亚洲变态另类AV首页，針對(duì)特殊圖（例如：二分圖、正則圖等等）的鄰接矩陣作了詳細(xì)介紹美日韩在线视频精品观看网站免费；最后中文字幕不卡免费视频，得到了利用圖計(jì)算矩陣的N次冪的方法久久片色大黄全免费网站，指出度數(shù)定理的實(shí)際應(yīng)用。

This thesis presents a systematic research on two types of graphs, that is undirected graph and mixed graph.

So with the adjacency matrix that has n vertices of a directed graph n2 units needed to store the adjacency matrix; on n vertices have an undirected graph Zexu into upper triangle, and only ...

因此用鄰接矩陣來表示一個(gè)具有n個(gè)頂點(diǎn)的有向圖時(shí)需要n2個(gè)單位來存儲(chǔ)鄰接矩陣人人爱人人摸人人干；對(duì)有n個(gè)頂點(diǎn)的無向圖則需存入上三角形，故只内射美女处女视频。男女无遮挡毛片视频免费播放。。

The multilevel partitioner of MVP achieves the better partitioning of weighted undirected graph by introducing the graph core during the coarsening phase,the spectral graph theory during the initial partitioning phase and swarm intelligence during the refinement phase.
