A combinatorial/geometric analysis of convex cyclofusene

摘要

Previously, we presented an algorithm for counting Kekulé structures for parallelogram-like benzenoids with holes by counting descending paths using rectangular meshes with holes. In this article, we describe an algorithm to count Kekulé structures for convex cyclofusenes using a combinatorial/geometric approach.
