New graph-theoretic algorithms were invented by Lederberg, Harold Brown, and others that generate all graphs with a specified set of nodes and connection-types (chemical atoms and bonds) -- with or without cycles.
Novi graf-teoretski algoritam su izmislili Lederberg, Harold Brown, i drugi koji stvaraju sve grafove sa određenim skupom čvorova i spojeva (kemijske atome i spojeve ) - sa ili bez ciklusa.
