In graph theory, a wheel graph is a graph formed by connecting a single universal vertex to all vertices of a cycle. A wheel graph with n vertices can also be defined as the 1-skeleton of an …

在 图论 这一 数学 分支中， 轮图 （wheel graph）是指一个 完全点 连接到一个 循环图 上所有节点而形成的图。 一些文献中 [1] 会使用记号 Wn 来表示有 n 个节点（n ≥ 4）的轮图；另一些文 …

The wheel W_n can be defined as the graph join K_1+C_(n-1), where K_1 is the singleton graph and... As defined in this work, a wheel graph W_n of order n, sometimes simply called an n …

當 n 為奇數時， Wn 是一個 完美圖 （英語：perfect graph），其 色數 為3：環上的節點可以用兩種顏色染色，而中間的完全點使用第三種顏色。 當 n 為偶數時， Wn 的 色數 為4，且當 n ≥ 6 …

WNTR can generate a NetworkX data object that stores network connectivity as a graph. The ability to easily integrate NetworkX with WNTR facilitates the use of numerous standard graph …

In this chapter we will discuss Complete graphs (Kn), complete bi-partite graphs (Kn,m), cycle graphs (Cn), wheel graphs (Wn), and star graphs (Sn). We have looked at many different …

2016年1月25日 · Let $G$ be a graph and let $k \in N$. The chromatic polynomial $P_G(k)$ is the number of distinct $k$-colourings if the vertices of G. Standard results for chromatic …
