• Graph isomorphism — In graph theory, an isomorphism of graphs G and H is a bijection between the vertex sets of G and H such that any two vertices u and v of G are adjacent in G if and only if ƒ(u) and ƒ(v) are adjacent in H. This kind of bijection is commonly… …   Wikipedia

• Graph labeling — In the mathematical discipline of graph theory, a graph labeling is the assignment of labels traditionally represented with integers to the edges or vertices, or both, of a graph. The labeling strategy depends on the category of the labeling.… …   Wikipedia
