Hamiltonian cycles in torical lattices [PDF]
Discrete Mathematics & Theoretical Computer Science, 2005 We establish sufficient conditions for a toric lattice $T_{m,n}$ to be Hamiltonian. Also, we give some asymptotics for the number of Hamiltonian cycles in $T_{m,n}$.

What do Eulerian and Hamiltonian cycles have to do with genome assembly? [PDF]
PLoS Computational Biology, 2021 Many students are taught about genome assembly using the dichotomy between the complexity of finding Eulerian and Hamiltonian cycles (easy versus hard, respectively).

Finding hidden hamiltonian cycles [PDF]
Random Structures & Algorithms, 1994 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

Hamiltonian Cycles in Polyhedral Maps [PDF]
Proceedings - Mathematical Sciences, 2014 We present a necessary and sufficient condition for existence of a contractible, non-separating and noncontractible separating Hamiltonian cycle in the edge graph of polyhedral maps on surfaces.

Complexity of Hamiltonian Cycle Reconfiguration [PDF]
Algorithms, 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 ...

On vertices enforcing a Hamiltonian cycle [PDF]
Discussiones Mathematicae Graph Theory, 2012 A nonempty vertex set X ⊆ V (G) of a hamiltonian graph G is called an H-force set of G if every X-cycle of G (i.e. a cycle of G containing all vertices of X) is hamiltonian. The H-force number h(G) of a graph G is defined to be the smallest cardinality of an H-force set of G.

Removable matchings and hamiltonian cycles
Discrete Mathematics, 2008 AbstractFor a graph G, let σ2(G) denote the minimum degree sum of two nonadjacent vertices (when G is complete, we let σ2(G)=∞). In this paper, we show the following two results: (i) Let G be a graph of order n≥4k+3 with σ2(G)≥n and let F be a matching of size k in G such that G−F is 2-connected.

Counting Traversing Hamiltonian Cycles in Tiled Graphs
Mathematics, 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.

An explicit construction of graphs of bounded degree that are far from being Hamiltonian [PDF]
Discrete Mathematics & Theoretical Computer Science, 2022 Hamiltonian cycles in graphs were first studied in the 1850s. Since then, an impressive amount of research has been dedicated to identifying classes of graphs that allow Hamiltonian cycles, and to related questions.
