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 ...

Colorful induced subgraphs

open access: yesDiscrete Mathematics, 1992
AbstractA colored graph is a graph whose vertices have been properly, though not necessarily optimally colored, with integers. Colored graphs have a natural orientation in which edges are directed from the end point with smaller color to the end point with larger color.

Advice Complexity of the Online Induced Subgraph Problem [PDF]

open access: yes, 2015
Several well-studied graph problems aim to select a largest (or smallest) induced subgraph with a given property of the input graph. Examples of such problems include maximum independent set, maximum planar graph, and many others.

Factors and induced subgraphs

open access: yesDiscrete Mathematics, 1988
AbstractIn [4] Katerinis proved the following: If G − x has a 2k-factor for each x ϵ V(G), then G has a 2k-factor.

Efficient Enumeration of Subgraphs and Induced Subgraphs with Bounded Girth [PDF]

open access: yes, 2018
The girth of a graph is the length of its shortest cycle. Due to its relevance in graph theory, network analysis and practical fields such as distributed computing, girth-related problems have been object of attention in both past and recent literature. In this paper, we consider the problem of listing connected subgraphs with bounded girth. As a large

Graphs containing finite induced paths of unbounded length [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2022
The age $\mathcal{A}(G)$ of a graph $G$ (undirected and without loops) is the collection of finite induced subgraphs of $G$, considered up to isomorphy and ordered by embeddability. It is well-quasi-ordered (wqo) for this order if it contains no infinite

Induced Subgraphs and Path Decompositions

open access: yesThe Electronic Journal of Combinatorics, 2023
A graph $H$ is an induced subgraph of a graph $G$ if a graph isomorphic to $H$ can be obtained from $G$ by deleting vertices. Recently, there has been significant interest in understanding the unavoidable induced subgraphs for graphs of large treewidth.

Reconfiguration of Regular Induced Subgraphs

open access: yes, 2022
We study the problem of checking the existence of a step-by-step transformation of $d$-regular induced subgraphs in a graph, where $d \ge 0$ and each step in the transformation must follow a fixed reconfiguration rule. Our problem for $d=0$ is equivalent to \textsc{Independent Set Reconfiguration}, which is one of the most well-studied reconfiguration ...

Mitigating Molecular Aggregation in Drug Discovery With Predictive Insights From Explainable AI

open access: yesAngewandte Chemie, EarlyView.
In this work, MEGAN, our explainable AI model, is applied to predict small colloidally aggregating molecules (SCAMs), a significant source of false positives in drug discovery. MEGAN provides interpretable predictions and proposes structurally similar, non‐aggregating alternative molecules.
