Define strongly connected graph
WebOct 29, 2014 · 1. By contradiction: suppose the graph is not connected, then it has at the very least 2 connected components, so the size of the smallest component is at most n 2 Meaning the degree of a vertex in that component is at most n 2 − 1 meaning the minimum degree is at most n 2 − 1. Thus a graph with minimum degree at least n 2 must be … WebA strongly connected component is the portion of a directed graph in which there is a path from each vertex to another vertex. It is applicable only on a directed graph. Let us take the graph below. You can observe that …
