Since the graph is complete, any permutation starting with a fixed vertex gives an (almost) unique cycle (the last vertex in the permutation will have an edge back to the first, fixed vertex. Except for one thing: if you visit the vertices in the cycle in reverse order, then that's really the same cycle (because of this, the number is half of ... Given an undirected graph with V vertices and E edges. Every node has been assigned a given value. The task is to find the connected chain with the maximum sum of values among all the …For a complete directed or undirected graph, the density is always .

Two edges are parallel if they connect the same pair of vertices. When an edge connects two vertices, we say that the vertices are adjacent to one another and that the edge is incident on both vertices.
