In graph theory, a loop (also called a self-loop or a buckle) is an edge that connects a vertex to itself. A simple graph contains no loops. Depending on the context, a graph or a multigraph may be defined so as to either allow or disallow the presence of loops (often in concert with allowing or disallowing multiple … See more For an undirected graph, the degree of a vertex is equal to the number of adjacent vertices. A special case is a loop, which adds two to the degree.

For example, 'keepselfloops' specifies that nodes with one or more self-loops will have one self-loop in the simplified graph.

For example: can be simplified by eliminating the self-loop. We multiply
WebA cycle in a graph is, according to Wikipedia, An edge set that has even degree at every vertex; also called an even edge set or, when taken together with its vertices, an even subgraph. In your case, the single vertex has a degree of 2, which is even.
