WebIn graph theory, a path in a graph is a sequence of vertices such that from each of its vertices there is an edge to the next vertex in the sequence. A path may be infinite, but a finite path always has a first vertex, called its start vertex, and a last vertex, called its end vertex.Both of them are called terminal vertices of the path. The other vertices in the … WebGraph theory is a branch of mathematics concerned about how networks can be encoded, and their properties measured. 1. Basic Graph Definition. A graph is a symbolic representation of a network and its connectivity. It implies an abstraction of reality so that it can be simplified as a set of linked nodes.

WebHonors Discovery Seminar: Graph Theory, Part II Definition.A graph is planar if we can draw it in the plane without any of the edges crossing. A face of a planar graph is a region bounded by the edges. We say that the region outside a graph is also a face. (For a more senisble version of this: draw your graph on a sphere, and then count the faces.) 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 …
