WebSep 1, 2024 · That means you need to remove at least n 2 edges from the complete graph. If you do this by pairing the vertices, you get a complete graph minus a perfect matching. That graph is Eulerian, and (because n is big enough) still has 2 different Hamiltonian cycles). So the answer here is ( n 2) − n 2 = n ( n − 2) 2. WebApr 6, 2024 · Terminologies of Graph Theory. A non-trivial graph includes one or more vertices (or nodes), joined by edges. Each edge exactly joins two vertices. The degree of a vertex is defined as the number of edges joined to that vertex. In the graph below, you will find the degree of vertex A is 3, the degree of vertex B and C is 2, the degree of vertex ...
