The Glasgow Subgraph Solver: Using Constraint Programming to Tackle Hard Subgraph Isomorphism Problem Variants [PDF]

open access: bronzeGraph Transformation13th International Conference, 2020
The Glasgow Subgraph Solver provides an implementation of state of the art algorithms for subgraph isomorphism problems. It combines constraint programming concepts with a variety of strong but fast domain-specific search and inference techniques, and is suitable for use on a wide range of graphs, including many that are found to be computationally ...

Recursive-Parallel Algorithm for Solving the Graph-Subgraph Isomorphism Problem

open access: diamondМоделирование и анализ информационных систем, 2022
The paper proposes a parallel algorithm for solving the Graph-Subgraph Isomorphism Problem and makes an experimental study of its efficiency. The problem is one of the most famous NP-complete problems.

SEARCH-TREE SIZE ESTIMATION FOR THE SUBGRAPH ISOMORPHISM PROBLEM [PDF]

open access: diamondActa Electrotechnica et Informatica, 2019
This article addresses the problem of finding patterns in graphs. This is formally defined as the subgraph isomorphism problem and is one of the core problems in theoretical computer science. We consider the counting variation of this problem.

The Subgraph Isomorphism Problem for Port Graphs and Quantum Circuits [PDF]

open access: greenarXiv.org, 2023
We study a variant of the subgraph isomorphism problem that is of high interest to the quantum computing community. Our results give an algorithm to perform pattern matching in quantum circuits for many patterns simultaneously, independently of the number of patterns. After a pre-computation step in which the patterns are compiled into a decision tree,

PathLAD+: An Improved Exact Algorithm for Subgraph Isomorphism Problem [PDF]

open access: bronzeProceedings of the Thirty-Second International Joint Conference on Artificial Intelligence, 2023
The subgraph isomorphism problem (SIP) is a challenging problem with wide practical applications. In the last decade, despite being a theoretical hard problem, researchers design various algorithms for solving SIP. In this work, we propose three main heuristics and develop an improved exact algorithm for SIP. First, we design a probing search procedure

An Improved Heuristic Method for Subgraph Isomorphism Problem [PDF]

open access: goldIOP Conference Series: Materials Science and Engineering, 2017
This paper focus on the subgraph isomorphism (SI) problem. We present an improved genetic algorithm, a heuristic method to search the optimal solution. The contribution of this paper is that we design a dedicated crossover algorithm and a new fitness function to measure the evolution process.

Efficient Implementation of Color Coding Algorithm for Subgraph Isomorphism Problem [PDF]

open access: greenAnalysis of Experimental Algorithms - Special Event, 2019
We consider the subgraph isomorphism problem where, given two graphs G (source graph) and F (pattern graph), one is to decide whether there is a (not necessarily induced) subgraph of G isomorphic to F. While many practical heuristic algorithms have been developed for the problem, as pointed out by McCreesh et al. [JAIR 2018], for each of them there are

GRAPH-SUBGRAPH ISOMORPHISM PROBLEM SOLVING FOR ORGANIZATION RESOURCES DISTRIBUTION

open access: diamondRadio Electronics, Computer Science, Control, 2014
The paper presents graph-analytical approach for organizations resources distribution. It based on graph-subgraph isomorphism algorithm for weighted and labeled graphs and can be considered as development of graph-subgraph isomorphism algorithm for weighted graphs proposed before.

OrbitSI: An Orbit-based Algorithm for the Subgraph Isomorphism Search Problem

open access: closed2024 IEEE International Conference on Knowledge Graph (ICKG)
The Subgraph Isomorphism (SI) search problem searches for embeddings of a pattern graph within a data graph. Efficient heuristic algorithms for the SI search problem are often structured around a Depth-First Search (DFS) tree-based search to find matching subgraphs.
