WebA 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: WebMaybe a good way to look at it is the adjacency matrix. In a regular graph, every row-sum is equal. In the stronger property I'm speculating about, perhaps every row is a rotation of every other? My reason for interest in this is in the context of genetic algorithms.
