Berge's graph

Berge's graph is a type of mathematical structure in graph theory where, for any subset of vertices with an odd number of elements, the total number of edges connecting them is even. In simpler terms, if you pick any odd-sized group of points in the graph, the number of connections between those points always turns out to be an even number. This property helps mathematicians analyze and classify specific graphs, leading to deeper insights into their structure and behavior, especially in understanding more complex relationships within networks.
