Below is an image in Figure 1 showing ...Euler Path. An Euler path is a path that uses every edge in a graph with no repeats. Being a path, it does not have to return to the starting vertex. Example. In the graph shown below, there are several Euler paths. One such path is CABDCB. The path is shown in arrows to the right, with the order of edges numbered.

In this ...A graph is said to be regular of degree r if all local degrees are the same number r. A 0-regular graph is an empty graph, a 1-regular graph consists of disconnected edges, and a two-regular graph consists of one or more (disconnected) cycles. The first interesting case is therefore 3-regular graphs, which are called cubic graphs (Harary 1994, pp. 14-15). …Explanation: In a complete graph of order n, there are n*(n-1) number of edges and degree of each vertex is (n-1). Hence, for a graph of order 9 there should be 36 edges in total. 7.Find all cliques of size K in an undirected graph. Given an undirected graph with N nodes and E edges and a value K, the task is to print all set of nodes which form a K size clique . A clique is a complete subgraph of a graph. Explanation: Clearly from the image, 1->2->3 and 3->4->5 are the two complete subgraphs.
Properties of Cycle Graph:-. It is a Connected Graph. A Cycle Graph or Circular Graph is a graph that consists of a single cycle. In a Cycle Graph number of vertices is equal to number of edges.
