Resilience for loose Hamilton cycles [PDF]

open access: diamondProcedia Computer Science, 2023
We study the emergence of loose Hamilton cycles in subgraphs of random hypergraphs. Our main result states that the minimum $d$-degree threshold for loose Hamiltonicity relative to the random $k$-uniform hypergraph $H_k(n,p)$ coincides with its dense analogue whenever $p \geq n^{- (k-1)/2+o(1)}$.

Constructing Hamilton cycles and perfect matchings efficiently [PDF]

open access: goldEuropean Conference on Combinatorics, Graph Theory and Applications, 2022
Starting with the empty graph on $[n]$, at each round, a set of $K=K(n)$ edges is presented chosen uniformly at random from the ones that have not been presented yet.

k-Ordered Hamilton cycles in digraphs [PDF]

open access: greenJournal of Combinatorial Theory, Series B, 2007
Given a digraph D, the minimum semi-degree of D is the minimum of its minimum indegree and its minimum outdegree. D is k-ordered Hamiltonian if for every ordered sequence of k distinct vertices there is a directed Hamilton cycle which encounters these vertices in this order.

Counting Hamilton Cycles in Dirac Hypergraphs

open access: yesCombinatorica, 2023
For $$0\le \ell 1 / 2 has (asymptotically and up to a subexponential factor) at least as many Hamilton $$\ell $$ ℓ -cycles as a typical random k -graph with edge-probability $$\delta $$ δ .

Perfect Matchings and Loose Hamilton Cycles in the Semirandom Hypergraph Model [PDF]

open access: hybridRandom Struct. Algorithms, 2023
We study the 2‐offer semirandom 3‐uniform hypergraph model on n$$ n $$ vertices. At each step, we are presented with 2 uniformly random vertices. We choose any other vertex, thus creating a hyperedge of size 3.

Hamilton Cycles in Double Generalized Petersen Graphs

open access: diamondDiscussiones Mathematicae Graph Theory, 2019
Coxeter referred to generalizing the Petersen graph. Zhou and Feng modified the graphs and introduced the double generalized Petersen graphs (DGPGs). Kutnar and Petecki proved that DGPGs are Hamiltonian in special cases and conjectured that all DGPGs are

Hamilton cycles in 3‐out [PDF]

open access: bronzeRandom Structures & Algorithms, 2009
AbstractLet G3‐out denote the random graph on vertex set [n] in which each vertex chooses three neighbors uniformly at random. Note that G3‐out has minimum degree 3 and average degree 6. We prove that the probability that G3‐out is Hamiltonian goes to 1 as n tends to infinity. © 2009 Wiley Periodicals, Inc. Random Struct.

An O(n) time algorithm for finding Hamilton cycles with high probability [PDF]

open access: greenInformation Technology Convergence and Services, 2020
We design a randomized algorithm that finds a Hamilton cycle in $\mathcal{O}(n)$ time with high probability in a random graph $G_{n,p}$ with edge probability $p\ge C \log n / n$.
