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 … WebGraph Theory iii GRAPH –BASIC PROPERTIES ... Loop In a graph, if an edge is drawn from vertex to itself, it is called a loop. Example 1 In the above graph, V is a vertex for which it has an edge (V, V) forming a loop. Example 2 In this graph, there are two loops which are formed at vertex a, and vertex b.
