Non-adaptive Group Testing on Graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2018
Grebinski and Kucherov (1998) and Alon et al. (2004-2005) study the problem of learning a hidden graph for some especial cases, such as hamiltonian cycle, cliques, stars, and matchings.

On subgraphs without large components [PDF]

open access: yesMathematica Bohemica, 2017
We consider, for a positive integer $k$, induced subgraphs in which each component has order at most $k$. Such a subgraph is said to be $k$-divided. We show that finding large induced subgraphs with this property is NP-complete.

Groups for which the noncommuting graph is a split graph [PDF]

open access: yesInternational Journal of Group Theory, 2017
The noncommuting graph $nabla (G)$ of a group $G$ is a simple graph whose vertex set is the set of noncentral elements of $G$ and the edges of which are the ones connecting two noncommuting elements. We determine here, up to isomorphism, the structure of

A Survey on the Densest Subgraph Problem and its Variants [PDF]

open access: yesACM Computing Surveys, 2023
The Densest Subgraph Problem requires us to find, in a given graph, a subset of vertices whose induced subgraph maximizes a measure of density. The problem has received a great deal of attention in the algorithmic literature since the early 1970s, with ...

Induced subgraph and eigenvalues of some signed graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2022
Hao Huang proved the Sensitivity Conjecture in [Induced graphs of the hypercube and a proof of the Sensitivity Conjecture, Annals of Mathematics, 190 (2019), 949-955] by signed graph spectral method.

On Minimal Unique Induced Subgraph Queries

open access: yesApplied Sciences, 2018
In this paper, a novel type of interesting subgraph query is proposed: Minimal Unique Induced Subgraph (MUIS) query. Given a (large) graph G and a query vertex (position) q in the graph, can we find an induced subgraph containing q with the minimal ...

Graphs in which every c edges that form a tree are chords of a common cycle

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Consider the k-connected graphs G in which every edges that form a particular type of induced subgraph must all be chords of a common cycle of G. Extending a few known partial results with and new results exploit the structure of the specified type of ...

Supervised chemical graph mining improves drug-induced liver injury prediction

open access: yesiScience, 2023
Summary: Drug-induced liver injury (DILI) is the main cause of drug failure in clinical trials. The characterization of toxic compounds in terms of chemical structure is important because compounds can be metabolized to toxic substances in the liver ...
