A path is a walk with no repeated vertices. A trail is a walk with no repeated edges. A tour is a walk that visits every vertex returning to its starting vertex. A tour could visit some vertices more than once. If you visit them exactly once, then the tour is a Hamiltonian cycle. A cycle is a walk in which the end vertex is the same as the ... WebMar 24, 2024 · A Hamiltonian path, also called a Hamilton path, is a graph path between two vertices of a graph that visits each vertex exactly once.

What you asked about is a walk which is not a path (according to the terminology in op. cit., which is quite in tune with usual contemporary graph-theoretic terminology, and has very clean notation and presentation ... WebIn graph theory, an Eulerian trail (or Eulerian path) is a trail in a finite graph that visits every edge exactly once (allowing for revisiting vertices). Similarly, an Eulerian circuit or Eulerian cycle is an Eulerian trail that starts and ends on the same vertex.They were first discussed by Leonhard Euler while solving the famous Seven Bridges of Königsberg …

In formal terms, a directed graph is an ordered pair G = (V, A) where • V is a set whose elements are called vertices, nodes, or points; • A is a set of ordered pairs of vertices, called arcs, directed edges (sometimes simply edges with the corresponding set named E instead of A), arrows, or directed lines. WebA Connected Graph A graph is said to be connected if any two of its vertices are joined by a path. A graph that is not connected is a disconnected graph. A disconnected graph is …

WebGraph theory is the study of mathematical objects known as graphs, which consist of vertices (or nodes) connected by edges.
