Computing and Drawing Isomorphic Subgraphs

open access: yesJournal of Graph Algorithms and Applications, 2004
Summary: The isomorphic subgraph problem is finding two disjoint subgraphs of a graph which coincide on at least \(k\) edges. The graph is partitioned into a subgraph, its copy, and a remainder. The problem resembles the NP-hard largest common subgraph problem, which searches copies of a graph in a pair of graphs.

Approximate subgraph matching-based literature mining for biomedical events and relations. [PDF]

open access: yesPLoS ONE, 2013
The biomedical text mining community has focused on developing techniques to automatically extract important relations between biological components and semantic events involving genes or proteins from literature.

Towards an Isomorphism Dichotomy for Hereditary Graph Classes [PDF]

open access: yes, 2014
In this paper we resolve the complexity of the isomorphism problem on all but finitely many of the graph classes characterized by two forbidden induced subgraphs.

Isomorphic subgraphs having minimal intersections [PDF]

open access: yesJournal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1983
AbstractGiven a finite graph H and G, a subgraph of it, we define σ (G, H) to be the largest integer such that every pair of subgraphs of H, both isomorphic to G, has at least σ(G, H) edges in common; furthermore, R(G, H) is defined to be the maximum number of subgraphs of H, all isomorphic to G, such that any two of them have σ(G, H) edges common ...

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 ...

Graph Homomorphism Revisited for Graph Matching [PDF]

open access: yes, 2010
In a variety of emerging applications one needs to decide whether a graph G matches another G p , i.e. , whether G

Mining Frequent Neighborhood Patterns in Large Labeled Graphs [PDF]

open access: yes, 2013
Over the years, frequent subgraphs have been an important sort of targeted patterns in the pattern mining literatures, where most works deal with databases holding a number of graph transactions, e.g., chemical structures of compounds. These methods rely

Recursive-Parallel Algorithm for Solving the Maximum Common Subgraph Problem

open access: yesМоделирование и анализ информационных систем, 2023
The paper proposes an algorithm for solving the problem of finding the maximum common subgraph. Both the sequential and the parallel version of the algorithm, their software implementation are described, and an experimental study of their effectiveness ...

A Multi-Dimensional Matrix Product—A Natural Tool for Parameterized Graph Algorithms

open access: yesAlgorithms, 2022
We introduce the concept of a k-dimensional matrix product D of k matrices A1,…,Ak of sizes n1×n,…,nk×n, respectively, where D[i1,…,ik] is equal to ∑ℓ=1nA1[i1,ℓ]×…×Ak[ik,ℓ].

Set-Centric Subgraph Isomorphism

open access: yes, 2021
We investigate techniques for accelerating subgraph isomorphism (SI). SI is the task of finding occurrences of a pattern graph in a target graph and relevant to many practical applications. Our key idea is to use set algebra based formulations of SI.
