WebSep 8, 2024 · 6. Consider a graph without self-loops. Suppose you can't see it, but you're told the degree of every node. Can you recreate it? In many cases the answer is "no," because the degree contains no information about which node a particular edge connects to. So the real question is this: should we pay attention to which node a self-loop … WebOct 31, 2024 · Figure 5.1. 1: A simple graph. A graph G = ( V, E) that is not simple can be represented by using multisets: a loop is a multiset { v, v } = { 2 ⋅ v } and multiple edges are represented by making E a multiset. The condensation of a multigraph may be formed by interpreting the multiset E as a set. A general graph that is not connected, has ...

WebMar 24, 2024 · A Hamiltonian cycle, also called a Hamiltonian circuit, Hamilton cycle, or Hamilton circuit, is a graph cycle (i.e., closed loop) through a graph that visits each node exactly once (Skiena 1990, p. 196). A graph possessing a Hamiltonian cycle is said to be a Hamiltonian graph. By convention, the singleton graph K_1 is considered to be … WebAug 8, 2024 · 4. Why does one count a loop as a double in graph degree? Rather than just as a single? From Wikipedia: a vertex with a loop "sees" itself as an adjacent vertex from both ends of the edge thus adding two, not one, to the degree. Or perhaps this is just a feature of undirected graphs.

Is a self-loop in directional graph considered as a cycle?

In graph theory, the degree (or valency) of a vertex of a graph is the number of edges that are incident to the vertex; in a multigraph, a loop contributes 2 to a vertex's degree, for the two ends of the edge. The degree of a vertex is denoted or . The maximum degree of a graph , denoted by , and the minimum degree of a graph, denoted by , are the maximum and minimum of its vertices' degrees.

If the definition is that edges e and f are adjacent if they have a common vertex, then a loop is adjacent to itself, but then every edge is also adjacent to itself. If e ≠ f is required, then loops aren't adjacent to themselves. – Randy Marsh.
