Graph theory cycle

http://www.categories.acsl.org/wiki/index.php?title=Graph_Theory WebCycle: A closed path in the graph theory is also known as a Cycle. A cycle is a type of closed walk where neither edges nor vertices are allowed to repeat. There is a possibility that only the starting vertex and ending vertex are the same in a cycle. So for a cycle, the following two points are important, which are described as follows: ...
