The Traveling Salesman Problem for Cubic Graphs
We show how to find a Hamiltonian cycle in a graph of degree at most three with n vertices, in time O(2n/3

Nomadic decompositions of bidirected complete graphs
We use K n to denote the bidirected complete graph on n vertices. A nomadic Hamiltonian decomposition of K n is a Hamiltonian decomposition, with the additional property that &quo...

Hamiltonian Cycles in Triangular Grids
We study the Hamiltonian Cycle problem in graphs induced by subsets of the vertices of the tiling of the plane with equilateral triangles. By analogy with grid graphs we call such...

A Sufficient Condition for Quasi-Claw-Free Hamiltonian Graphs
Abstract. There are several well-known and important hamiltonian results for claw-free graphs but only a few are concerned with quasi-claw-free graphs. In this note, we provide a n...

2-Factors in Hamiltonian Graphs
We show that every hamiltonian claw-free graph with a vertex x of degree d(x) 7 has a 2-factor consisting of exactly two cycles.
