Complete graph edges.
Find all cliques of size K in an undirected graph. Given an undirected graph with N nodes and E edges and a value K, the task is to print all set of nodes which form a K size clique . A clique is a complete subgraph of a graph. Explanation: Clearly from the image, 1->2->3 and 3->4->5 are the two complete subgraphs.

A weighted graph is a graph where the edges have weights. Degree: The degree of a vertex is the number of edges that connect to it. In a directed graph, the in-degree of a vertex is the number of edges that point to it, and the out-degree is the number of edges that start from it. Path: A path is a sequence of vertices that are connected by …
Euler Path. An Euler path is a path that uses every edge in a graph with no repeats. Being a path, it does not have to return to the starting vertex. Example. In the graph shown below, there are several Euler paths. One such path is CABDCB. The path is shown in arrows to the right, with the order of edges numbered.
To extrapolate a graph, you need to determine the equation of the line of best fit for the graph’s data and use it to calculate values for points outside of the range.

The complete bipartite graph, \(K_{m,n}\), is the bipartite graph on \(m + n\) vertices with as many edges as possible subject to the constraint that it has a bipartition into sets of cardinality \(m\) and \(n\). That is, it has every edge between the two sets of the bipartition.
