Web4.A path is a graph G is a finite sequence of verticesv 0,v 1,···,v t such that v i is adjacent to v i+1. The number t of edges is the length of the path. 5.A cycle is a path with v t = v 0. 6.A graph is connected if for every pair of vertices v and w, there is a path from v to w. A graph is disconnected if it is not connected. 7.Let G = (V ...

WebAug 19, 2024 · A graph is said to be complete if it’s undirected, has no loops, and every pair of distinct nodes is connected with only one edge. Also, we can have an n-complete graph Kn depending on the number of vertices. Example of the first 5 complete graphs. We should also talk about the area of graph coloring.

A line between the names of two people means that they know each other. If there's no line between two names, then the people do not know each other. The relationship "know each other" goes both ways; for example, because Audrey knows Gayle, that means Gayle knows Audrey. This social network is a graph.
