'edges' – augments a fixed number of vertices by adding one edge. In this case, all graphs on exactly n=vertices are generated. If for any graph G satisfying the property, every subgraph, obtained from G by deleting one edge but not the vertices incident to that edge, satisfies the property, then this will generate all graphs with that property. Then the Tutte polynomial, also known as the dichromate or Tutte-Whitney polynomial, is defined by. (1) (Biggs 1993, p. 100). An equivalent definition is given by.
