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. WebIn graph theory, a cycle graph or circular graph is a graph that consists of a single cycle, or in other words, some number of vertices (at least 3, if the graph is simple) connected in a closed chain.The cycle graph with n vertices is called C n. The number of vertices in C n equals the number of edges, and every vertex has degree 2; that is, every vertex has …
