What does "Central Vertex" mean?
Table of Contents
A central vertex is a special point in a graph that acts like the heart of the structure. Imagine a party where everyone is trying to find the best place to hang out. The central vertex is that perfect spot where the most people can gather with the least effort. It connects to other vertices, or points, in a way that makes it easier for everyone to reach them.
In technical terms, the central vertex is often the one that has the smallest maximum distance to all other vertices. In simpler words, if you are standing at the central vertex, you can get to everyone else faster than if you were standing on any other point.
