Fully-connected graphs mean we have ‘true’ edges from the original graph and ‘fake’ edges added from the fully-connected transformation, and we want to distinguish those. Even more importantly, we need a way to imbue nodes with some positional features, otherwise GTs fall behind GNNs (as shown in the 2020 paper of Dwivedi and Bresson ).Clique - Fully connected component - a subset of the vertices of a Graph that are fully connected. Strongly connected - For a Directed Graph, for every pair of vertices x, y in V a path from x to y implies a path from y to x.Case 1: Consider a graph with only vertices and a few edges, sparsely connected graph (100 vertices and 2 edges). In that case, the segment 1 would dominate the course of traversal. Hence making, O(V) as the time complexity as segment 1 checks all vertices in graph space once. Therefore, T.C. = O(V) (since E is negligible).Connected Graph: A graph will be known as a connected graph if it contains two vertices that are connected with the help of a path.
