Beating Treewidth for Average-Case Subgraph Isomorphism [PDF]

open access: yesAlgorithmica, 2021
For any fixed graph $G$, the subgraph isomorphism problem asks whether an $n$-vertex input graph has a subgraph isomorphic to $G$. A well-known algorithm of Alon, Yuster and Zwick (1995) efficiently reduces this to the "colored" version of the problem, denoted $G$-$\mathsf{SUB}$, and then solves $G$-$\mathsf{SUB}$ in time $O(n^{tw(G)+1})$ where $tw(G)$

A Method for the Quality‐Aware Automated Selection of Deployment Technologies

open access: yesSoftware: Practice and Experience, Volume 55, Issue 11, Page 1855-1876, November 2025.
ABSTRACT Domain The deployment of distributed multi‐component cloud applications typically requires a combination of multiple heterogeneous deployment technologies. A different combination of deployment technologies should be chosen due to varying deployment qualities, such as the functional suitability and reliability of the deployment technologies ...

Number of Subgraphs and Their Converses in Tournaments and New Digraph Polynomials

open access: yesJournal of Graph Theory, Volume 110, Issue 2, Page 127-131, October 2025.
ABSTRACT An oriented graph D is converse invariant if, for any tournament T, the number of copies of D in T is equal to that of its converse − D. El Sahili and Ghazo Hanna [J. Graph Theory 102 (2023), 684‐701] showed that any oriented graph D with maximum degree at most 2 is converse invariant. They proposed a question: Can we characterize all converse

On Endomorphism Universality of Sparse Graph Classes

open access: yesJournal of Graph Theory, Volume 110, Issue 2, Page 223-244, October 2025.
ABSTRACT We show that every commutative idempotent monoid (a.k.a. lattice) is the endomorphism monoid of a subcubic graph. This solves a problem of Babai and Pultr and the degree bound is best‐possible. On the other hand, we show that no class excluding a minor can have all commutative idempotent monoids among its endomorphism monoids. As a by‐product,

MODIT: MOtif DIscovery in Temporal Networks

open access: yesFrontiers in Big Data, 2022
Temporal networks are graphs where each edge is linked with a timestamp, denoting when an interaction between two nodes happens. According to the most recently proposed definitions of the problem, motif search in temporal networks consists in finding and

Longest cycles in vertex‐transitive and highly connected graphs

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2975-2990, October 2025.
Abstract We present progress on three old conjectures about longest paths and cycles in graphs. The first pair of conjectures, due to Lovász from 1969 and Thomassen from 1978, respectively, states that all connected vertex‐transitive graphs contain a Hamiltonian path, and that all sufficiently large such graphs even contain a Hamiltonian cycle.

GRAPES-DD: exploiting decision diagrams for index-driven search in biological graph databases

open access: yesBMC Bioinformatics, 2021
Background Graphs are mathematical structures widely used for expressing relationships among elements when representing biomedical and biological information. On top of these representations, several analyses are performed. A common task is the search of
