WebIn the mathematical discipline of graph theory, a graph labelling is the assignment of labels, traditionally represented by integers, to edges and/or vertices of a graph. [1] Formally, given a graph G = (V, E), a vertex labelling is a function of V to a set of labels; a graph with such a function defined is called a vertex-labeled graph. 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].
