Finding the number of cyclic isomers algorithmically Is there an algorithm for finding the number of cyclic isomers a given compound might have?

I've found a general algorithm for all isomers: link, but I'm not sure how to apply it for cyclic isomers only.
If I remember correctly, several years ago I stumbled over the SMOG program addressing this question (description here).  The software requestested sum formula and a selection of allowed structural elements, cyclic substructures were among them.  Maybe the algorithms implemented are not the first ones to answer such a question, yet publications like this showcase continuing interest in this field, too.
