So, it fails the definition of a function where each input can have only one ouput.Kn has n(n - 1)/2 edges (a triangular number ), and is a regular graph of degree n - 1. All complete graphs are their own maximal cliques. They are maximally connected as the only vertex cut which disconnects the graph is the complete set of vertices.

5.7 Connectivity. [Jump to exercises] We have seen examples of connected graphs and graphs that are not connected. While "not connected'' is pretty much a dead end, there is much to be said about "how connected'' a connected graph is. The simplest approach is to look at how hard it is to disconnect a graph by removing vertices or edges.Stack Exchange network consists of 183 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers..

KGraph is a library for k-nearest neighbor (k-NN) graph construction and online k-NN search using a k-NN Graph as index. KGraph implements heuristic algorithms that are extremely generic and fast: KGraph works on abstract objects. The only assumption it makes is that a similarity score can be computed on any pair of objects, with a user ... The graphs \(K_5\) and \(K_{3,3}\) are two of the most important graphs within the subject of planarity in graph theory. Kuratowski’s theorem tells us that, if we can find a subgraph in any graph that is homeomorphic to \(K_5\) or \(K_{3,3}\), then the graph is not planar, meaning it’s not possible for the edges to be redrawn such that they are …
