The path is shown in arrows to the right, with the order of edges numbered.

Complete directed graphs are simple directed graphs where each pair of vertices is joined by a symmetric pair of directed arcs (it is equivalent to an undirected complete graph with the edges replaced by pairs of inverse arcs). It follows that a complete digraph is symmetric.Simply, the undirected graph has two directed edges between any two nodes that, in the directed graph, possess at least one directed edge. This condition is a bit restrictive but it allows us to compare the entropy of the two graphs in general terms. We can do this in the following manner. 5.2. A Comparison of Entropy in Directed and Undirected ...To the right is K5, the complete (un-directed) graph of 5 nodes. A complete directed graph of n nodes has n(n–1) edges, since from each node there is a directed edge to each of the others. You can change this complete directed graph into a complete undirected graph by replacing the two directed edges between two nodes by a single undirected edge.

The complete graph with graph vertices is denoted and has (the triangular numbers) undirected edges, where is a binomial coefficient. In older literature, complete graphs are sometimes called universal graphs.An undirected graph is acyclic (i.e., a forest) if a DFS yields no back edges. Since back edges are those edges ( u, v) connecting a vertex u to an ancestor v in a depth-first tree, so no back edges means there are only tree edges, so there is no cycle. So we can simply run DFS. If find a back edge, there is a cycle.Undirected Graph. The undirected graph is also referred to as the bidirectional. It is a set of objects (also called vertices or nodes), which are connected together. Here the edges will be bidirectional. The two nodes are connected with a line, and this line is known as an edge. The undirected graph will be represented as G = (N, E).
