2. Two long-standing problems in graph theory Two long-standing problems in graph theory are the skew partition problem and the clique graph problem. The skew partition problem was defined by Chvátal in 1985 as the recognition problem for a special decomposition arising in the context of perfect...
These are some Concepts which everyone should know and are widely used in Graph Theory. Chromatic Number: Minimum number of colors required to color Graph G such that no two adjacent vertex gets same color. Brooks' Therorem: For any connected undirected graph G with maximum degree Δ, the ch...

Extremal problems in graph theory The aim of this note is to give an account of some recent results and state a number of conjectures concerning extremal properties of graphs. Béla,Bollobás - 《Journal of Graph Theory》 被引量: 301发表: 1977年 On state-dependent dynamic graphs and their ...
In this article, we show how, using graph theory, we can make a content analysis of political discourse. Assumptions of this analysis are: • we have a corpus of speech of each party or candidate; • we consider that speech conveys economic, political, socio-cultural values,...

graph theory 以图为研究对象的数学分支。图论中的图指的是一些点以及连接这些点的线的总体。通常用点代表事物,用连接两点的线代表事物间的关系、图论则是研究事物对象在上述表示法中具有的特征与性质的学科 。图论的发展已有200多年的历史,它发源于18世纪普鲁士的柯尼斯堡。当地的居民想知道能否从任意一陆地出发 ,...
