Hamiltonicity in Semi-Regular Tessellation Dual Graphs

Published 30 Sep 2019 in cs.CC and cs.CG | (1909.13755v1)

Abstract: This paper shows NP-completeness for finding Hamiltonian cycles in induced subgraphs of the dual graphs of semi-regular tessilations. It also shows NP-hardness for a new, wide class of graphs called augmented square grids. This work follows up on prior studies of the complexity of finding Hamiltonian cycles in regular and semi-regular grid graphs.
