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 ); however, the first textbook on graph theory appeared only in 1936, by Dénes Kőnig ( Konig, 1936 ). The paper written by Leonhard Euler on the Seven Bridges of Königsberg and published in 1736 is regarded as the first paper in the history of graph theory. This paper, as well as the one written by Vandermonde on the knight problem, carried on with the analysis situs initiated by Leibniz.
