"WebNov 5, 2024 · Nov 5, 2024 at 7:19. 1. It depends how adjacent edges are defined. 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. " - Graph theory loop

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 … 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 …
