Introduction to Graph Theory (6 pages) Starting with three motivating problems, this tutorial introduces the definition of graph along with the related terms: vertex (or node), edge (or arc), loop, degree, adjacent, path, circuit, planar, connected and component. Euler Circuits and Paths Coloring Problems (6 pages) Adjacency Matrices (Not yet available.) Part 5: From Trees to Graphs. Scott Mitchell 4GuysFromRolla.com Update January 2005 Summary: A graph, like a tree, is a collection of nodes and edges, but has no rules dictating the connection among the nodes. In this fifth part of the article series, we'll learn all about graphs, one of the most versatile data structures.(22 printed pages) Download the DataStructures20.msi sample file.
Editor's note This six-part article series originally appeared on MSDN Online starting in November 2003. Note This article assumes the reader is familiar with C#. Contents Introduction Starting from any node, any other node in the tree can be reached. In Part 3 we focused on binary trees, which are a special form of trees.
In this fifth installment of the article series, we're going to examine graphs. Note Realize that all trees are graphs. Figure 1 shows three examples of graphs. Figure 1. Many real-world problems can be modeled using graphs. Examining the Different Classes of Edges Directed and Undirected Edges Figure 2. Figure 3.
