Counting Hamilton Cycles in Dirac Hypergraphs
AbstractFor $$0\le \ell <k$$ 0 ≤ ℓ < k , a Hamilton $$\ell $$ ℓ -cycle in a k-uniform hypergraph H is a cyclic ordering of the vertices of H in which the edges ...

Hamilton cycles in almost distance-hereditary graphs
Let G be a graph on n ≥ 3 vertices. A graph G is almost distance-hereditary if each connected induced subgraph H of G has the property dH(x, y) ≤ dG(x, y) + 1 for any pair of vertices x, y ∈ V(H).

Path separation by short cycles
Two Hamilton paths in $K_n$ are separated by a cycle of length $k$ if their union contains such a cycle. For small fixed values of $k$ we bound the asymptotics of the maximum cardinality of a family of Hamilton paths in $K_n$ such that any pair of paths ...

A Note on Barnette’s Conjecture
Barnette conjectured that each planar, bipartite, cubic, and 3-connected graph is hamiltonian. We prove that this conjecture is equivalent to the statement that there is a constant c > 0 such that each graph G of this class contains a path on at least c ...

Cards of fixed points of some Lotka-Volterra operators [PDF]
The paper considers a special type of the Lotka-Volterra operator operating in a four-dimensional simplex. The tournament corresponding to this operator has four cyclic triples. All kinds of fixed point cards are built for it. It is proved which types of

Color‐biased Hamilton cycles in random graphs
AbstractWe prove that a random graph , with p above the Hamiltonicity threshold, is typically such that for any r‐coloring of its edges there exists a Hamilton cycle with at least edges of the same color. This estimate is asymptotically optimal.

Parameterized TSP: Beating the Average [PDF]
In the Travelling Salesman Problem (TSP), we are given a complete graph $K_n$ together with an integer weighting $w$ on the edges of $K_n$, and we are asked to find a Hamilton cycle of $K_n$ of minimum weight.

The results demonstrate a simulation‐driven workflow that applies LSB topology optimization with additive manufacturing constraints to mission‐specific load cases, integrating European Cooperation for Space Standardization compliant verification and manufacturability to develop structurally efficient rover suspension components.

Notes on sufficient conditions for a graph to be Hamiltonian
The first part of this paper deals with an extension of Dirac's Theorem to directed graphs. It is related to a result often referred to as the Ghouila-Houri Theorem.
