A graph and its complement are paths - Mathematics Stack Exchange

WebApr 24, 2024 · 1. The complement of a graph is what you get when you replace (a) all the edges with non-edges, and (b) all the non-edges with edges. So, here's the 4-node path and its complement: The complement also happens to be a path. The complement of a path on 2 nodes is the null graph on 2 nodes (i.e., 2 nodes, no edges), drawn below. WebIn the mathematical field of graph theory, the distance between two vertices in a graph is the number of edges in a shortest path (also called a graph geodesic) connecting them. This is also known as the geodesic distance or shortest-path distance. [1] Notice that there may be more than one shortest path between two vertices. [2] dan andrews weather
