Graphs - Definition

Graphs - Definition. G(V,E) - graph with vertex set V and edge set E E ? {(a,b)| a ? V and b ? V} - for directed graphs E ? {{a,b}| a ? V and b ? V} - for undirected graphs w: E ? R - weight function |V| - number of vertices |E| - number of edges

Theory of Computing. Lecture 6 MAS 714 Hartmut Klauck. Traversing Graphs. We are given a graph G=(V,E) Starting vertex s The goal is to traverse the graph , i.e., to visit each vertex at least once For example to find a marked vertex t or decide if t is reachable from s

Graphs: Traversal

Graphs: Traversal. Searching/Traversing a graph = visiting the vertices of a graph by following the edges in a systematic way Example : Given a highway map, find a path from one city to another. What if the graph has cycles?
