Polymer informatics: Integrating data‐driven strategies, advanced machine learning, and automated synthesis for next‐generation polymer design

open access: yesInfoScience, EarlyView.
Designing new polymers for applications such as sustainable plastics, biomaterials, and 3D printing has traditionally been slow and expensive, relying heavily on trial‐and‐error experiments. This review shows how polymer informatics—the integration of large polymer databases, machine‐learning models, and automated robotic synthesis—enables fast ...

Efficient enumeration of maximal k-degenerate induced subgraphs of a chordal graph [PDF]

open access: yes, 2018
In this paper we consider the problem of listing the maximal k-degenerate induced subgraphs of a chordal graph, and propose an output-sensitive algorithm using delay O(m⋅ω(G)) for any n-vertex chordal graph with m edges, where ω(G)≤n is the maximum size ...

Matching book thickness of generalized Petersen graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2022
The matching book embedding of a graph G is to place its vertices on the spine, and arrange its edges on the pages so that the edges in the same page do not intersect each other and the edges induced subgraphs of each page are 1-regular.

Well quasi-order in combinatorics : embeddings and homomorphisms

open access: yes, 2015
The notion of well quasi-order (wqo) from the theory of ordered sets often arises naturally in contexts where one deals with infinite collections of structures which can somehow be compared, and it then represents a useful discriminator between ‘tame ...

On regular induced subgraphs of edge-regular graphs. [PDF]

open access: yes, 2020
PhD Thesis.We study edge-regular graphs and their regular induced subgraphs. More precisely, we are interested in vertex partitions of edge-regular graphs into two parts, for which one or both of the parts induce a regular subgraph.

Induced subgraphs and tree decompositions V. one neighbor in a hole

open access: yes, 2022
What are the unavoidable induced subgraphs of graphs with large treewidth? It is well-known that the answer must include a complete graph, a complete bipartite graph, all subdivisions of a wall and line graphs of all subdivisions of a wall (we refer to ...

Signed Projective Cubes, a Homomorphism Point of View

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT The (signed) projective cubes, as a special class of graphs closely related to the hypercubes, are on the crossroad of geometry, algebra, discrete mathematics and linear algebra. Defined as Cayley graphs on binary groups, they represent basic linear dependencies.

Cuts and Induced Bipartite Subgraphs

open access: yes, 2017
In this chapter we compare three popular models for the maximum cut problem and show the equivalence of their relaxations by using compact extended formulations. These problems are closely related to the subject of edge-induced and node-induced bipartite

Fractional Balanced Chromatic Number and Arboricity of Planar (Signed) Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT A balanced ( p , q ) $(p,q)$‐coloring of a signed graph ( G , σ ) $(G,\sigma )$ is an assignment of q $q$ colors to each vertex of G $G$ from a platter of p $p$ colors, such that each color class induces a balanced set (a set that does not induce a negative cycle).

On the validity of Lovász’s inequality for induced star-perfect graphs

open access: yesJournal of Inequalities and Applications
Let F $\mathcal{F}$ be a family of graphs. For a graph G, define θ F ( G ) $\theta _{F}(G)$ as the minimum number of induced subgraphs of G, each isomorphic to a member of F $\mathcal{F}$ , needed to cover V ( G ) $V(G)$ , and α F ( G ) $\alpha _{F}(G ...
