However, … WebAug 19, 2024 · A graph is said to be complete if it’s undirected, has no loops, and every pair of distinct nodes is connected with only one edge. Also, we can have an n-complete graph Kn depending on the number of vertices. Example of the first 5 complete graphs. We should also talk about the area of graph coloring. sim settlements 2 performance
