Graph theoretic methods for the analysis of structural relationships in biological macromolecules [PDF]

open access: yes, 2005
Subgraph isomorphism and maximum common subgraph isomorphism algorithms from graph theory provide an effective and an efficient way of identifying structural relationships between biological macromolecules.

The search for minimal edge 1-extension of an undirected colored graph [PDF]

open access: yesИзвестия Саратовского университета. Новая серия. Серия Математика. Механика. Информатика, 2021
Let $G=(V, \alpha, f)$ be a colored graph with a coloring function $f$ defined on its vertices set $V$. Colored graph $G^*$ is an edge $1$-extension of a colored graph $G$ if $G$ could be included into each subgraph taking into consideration the colors ...

Pattern matching and pattern discovery algorithms for protein topologies [PDF]

open access: yes, 2001
We describe algorithms for pattern matching and pattern learning in TOPS diagrams (formal descriptions of protein topologies). These problems can be reduced to checking for subgraph isomorphism and finding maximal common subgraphs in a restricted ...

Two graph isomorphism polytopes [PDF]

open access: yes, 2008
The convex hull $\psi_{n,n}$ of certain $(n!)^2$ tensors was considered recently in connection with graph isomorphism. We consider the convex hull $\psi_n$ of the $n!$ diagonals among these tensors. We show: 1. The polytope $\psi_n$ is a face of $\psi_{n,

Performance and scalability of indexed subgraph query processing methods [PDF]

open access: yes, 2015
Graph data management systems have become very popular as graphs are the natural data model for many applications. One of the main problems addressed by these systems is subgraph query processing; i.e., given a query graph, return all graphs that ...

An Optimization of Closed Frequent Subgraph Mining Algorithm

open access: yesCybernetics and Information Technologies, 2017
Graph mining isamajor area of interest within the field of data mining in recent years. Akey aspect of graph mining is frequent subgraph mining. Central to the entire discipline of frequent subgraph mining is the concept of subgraph isomorphism.

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 ...

Domination Numbers of Amalgamations of Cycles at Connected Subgraphs

open access: yesJournal of Mathematics, 2022
A set S of vertices of a graph G is a dominating set of G if every vertex in VG is adjacent to some vertex in S. A minimum dominating set in a graph G is a dominating set of minimum cardinality.

Qubit Mapping Based on Subgraph Isomorphism and Filtered Depth-Limited Search [PDF]

open access: yesIEEE transactions on computers, 2020
Mapping logical quantum circuits to Noisy Intermediate-Scale Quantum (NISQ) devices is a challenging problem which has attracted rapidly increasing interests from both quantum and classical computing communities. This article proposes an efficient method
