WebGraph theory is an ancient discipline, the first paper on graph theory was written by Leonhard Euler in 1736, proposing a solution for the Königsberg bridge problem (Euler, 1736); From: Handbook of Energy Economics and Policy, 2024 View all Topics Add to Mendeley About this page Graph Theory WebA graph with six vertices and seven edges. In discrete mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related". The objects correspond to mathematical abstractions called vertices (also called nodes or points) and each of the related ...
