Graph theory connectivity
WebTake a look at the following graphs −. Graph I has 3 vertices with 3 edges which is forming a cycle ‘ab-bc-ca’. Graph II has 4 vertices with 4 edges which is forming a cycle ‘pq-qs-sr-rp’. Graph III has 5 vertices with 5 edges which is forming a cycle ‘ik-km-ml-lj-ji’. Hence all the given graphs are cycle graphs. Web2 GRAPH THEORY { LECTURE 4: TREES 1.

WebThe graph theory can be described as a study of points and lines. Graph theory is a type of subfield that is used to deal with the study of a graph. With the help of pictorial representation, we are able to show the mathematical truth. The relation between the nodes and edges can be shown in the process of graph theory.
