Web10.1 graph theory—origin Graph theory emerged in 1736 when Euler addressed the problem of walking across the seven bridges of Königsberg without crossing any bridge twice [1]. Euler used the benefits of graph theory to conclude that it was impossible to walk through the city crossing each bridge only once.
