Abstract
Graph analysis refers to the set of algorithms for analyzing properties of a graph. The main algorithms for graph analysis and traversal are introduced in this chapter. We start by discussing graph traversal, i.e., the problem of visiting the nodes of a graph. Many algorithms of graph analysis are based on a extension or modification of graph traversal algorithms. We then discuss the ways to find a shortest path among nodes in a graph. We also consider the compression of graphs through power graph analysis and the discovery of communities (i.e., a subgraph having some given properties). Node centrality measures, used for finding vital nodes are also discussed. We demonstrate the use of various graph traversal and analysis methods using R libraries.
