J. Pospichal et V. Kvasnicka, AN ALTERNATIVE APPROACH FOR CONSTRUCTIVE ENUMERATION OF GRAPHS, Collection of Czechoslovak Chemical Communications, 58(4), 1993, pp. 754-774
An efficient method for constructive enumeration of graphs is suggeste
d. The method is based on the so-called semicanonical numbering of gra
phs, that is a numbering much more restrictive than the cooperative nu
mbering. Graph-theoretical properties of the semicanonical numbering m
ake it possible to formulate an exhaustive and nonredundant constructi
ve enumeration of graphs. The approach allows an easy introduction of
specifications for molecular graphs.
