WebAug 16, 2024 · Definition 9.4. 2: Hamiltonian Path, Circuit, and Graphs. A Hamiltonian path through a graph is a path whose vertex list contains each vertex of the graph exactly once, except if the path is a circuit, in which case the initial vertex appears a second time as the terminal vertex. If the path is a circuit, then it is called a Hamiltonian circuit.

WebIn a directed graph, we can speak of the indegree (the number of edges coming in to the vertex) and the outdegree (the number of edges going out). Vertex a in graph G (above) has indegree 1 and outdegree 2. 1. Each vertex in the diagram below represents a web page on the topic of twelve-tone music. WebIn a directed graph, one can distinguish the outdegree (number of outgoing edges), denoted 𝛿 + (v), from the indegree (number of incoming edges), denoted 𝛿 − (v); a source vertex is a vertex with indegree zero, while a sink vertex is a vertex with outdegree zero.
