Complexity of Hamiltonian Cycle Reconfiguration [PDF]

open access: yesAlgorithms, 2018
The Hamiltonian cycle reconfiguration problem asks, given two Hamiltonian cycles C 0 and C t of a graph G, whether there is a sequence of Hamiltonian cycles C 0 , C 1 , … , C t such that C i can be obtained ...

Counting Traversing Hamiltonian Cycles in Tiled Graphs

open access: yesMathematics, 2023
Recently, the problem of counting Hamiltonian cycles in 2-tiled graphs was resolved by Vegi Kalamar, Bokal, and Žerak. In this paper, we continue our research on generalized tiled graphs.

Finding hidden hamiltonian cycles [PDF]

open access: yesRandom Structures & Algorithms, 1991
AbstractConsider a random graph G composed of a Hamiltonian cycle on n labeled vertices and dn random edges that “high” the cycle. Is it possible to unravel the structures, that is, to efficiently find a Himiltonian cycle in G? We describe an O(n3 log n)‐step algorithm A for this purpose, and prove that it succeeds almost surely. Part one of A properly

Two Hamiltonian cycles

open access: yesDiscrete Mathematics, 2022
If the line graph of a graph $G$ decomposes into Hamiltonian cycles, what is $G$? We answer this question for decomposition into two cycles.

Finding Hamiltonian and Longest (s,t)-Paths of C-Shaped Supergrid Graphs in Linear Time

open access: yesAlgorithms, 2022
A graph is called Hamiltonian connected if it contains a Hamiltonian path between any two distinct vertices. In the past, we proved the Hamiltonian path and cycle problems for general supergrid graphs to be NP-complete.

Hamiltonian Cycle Problem in Strong k-Quasi-Transitive Digraphs With Large Diameter

open access: yesDiscussiones Mathematicae Graph Theory, 2021
Let k be an integer with k ≥ 2. A digraph is k-quasi-transitive, if for any path x0x1... xk of length k, x0 and xk are adjacent. Let D be a strong k-quasi-transitive digraph with even k ≥ 4 and diameter at least k +2.

Extending Complex Conjugate Control to Nonlinear Wave Energy Converters

open access: yesJournal of Marine Science and Engineering, 2020
This paper extends the concept of Complex Conjugate Control (CCC) of linear wave energy converters (WECs) to nonlinear WECs by designing optimal limit cycles with Hamiltonian Surface Shaping and Power Flow Control (HSSPFC).

Enumerating Hamiltonian Cycles [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2014
A dynamic programming method for enumerating hamiltonian cycles in arbitrary graphs is presented. The method is applied to grid graphs, king's graphs, triangular grids, and three-dimensional grid graphs, and results are obtained for larger cases than previously published.

Reducing the generalised Sudoku problem to the Hamiltonian cycle problem

open access: yesAKCE International Journal of Graphs and Combinatorics, 2016
The generalised Sudoku problem with N symbols is known to be NP-complete, and hence is equivalent to any other NP-complete problem, even for the standard restricted version where N is a perfect square.
