OrbitSI: An Orbit-based Algorithm for the Subgraph Isomorphism Search Problem
2024 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.

Solving Graph Homomorphism and Subgraph Isomorphism Problems Faster Through Clique Neighbourhood Constraints [PDF]
Proceedings of the Thirtieth International Joint Conference on Artificial Intelligence, 2021 Graph homomorphism problems involve finding adjacency-preserving mappings between two given graphs. Although theoretically hard, these problems can often be solved in practice using constraint programming algorithms. We show how techniques from the state-of-the-art in subgraph isomorphism solving can be applied to broader graph homomorphism problems ...

HyGraph: a subgraph isomorphism algorithm for efficiently querying big graph databases
Journal of Big Data, 2022 The big graph database provides strong modeling capabilities and efficient querying for complex applications. Subgraph isomorphism which finds exact matches of a query graph in the database efficiently, is a challenging problem.

Theoretical Computer Science, 1989 AbstractWe consider the problems of subgraph homeomorphism with fixed pattern, disjoint connecting paths with bounded number of terminal pairs, recognition, and subgraph isomorphism for some classes of planar graphs. Following the results of Robertson and Seymour on forbidden minor characterization, we show that the first three of the above problems ...

The subgraph isomorphism problem for outerplanar graphs
Theoretical Computer Science, 1982 AbstractThis paper deals with the subgraph isomorphism problem for outerplanar graphs (SUBOUTISOM). In general, since trees and forests are outerplanar, SUBOUTISOM is NP-complete. We show that SUBOUTISOM remains NP-complete even when the strongest connectivity requirements are imposed on both graphs.

GRAPH-SUBGRAPH ISOMORPHISM PROBLEM SOLVING FOR DESIGNING SPECIAL COMPUTERS
Radio Electronics, Computer Science, Control, 2012 An advanced algorithm for solving graphs isomorphism problem is proposed and experimental results of its efficiency are presented. Object of investigation is set of control flow graphs of solutions achieved, that were received after circumvent of the semantic network by Warren abstract machine.

The Subgraph Isomorphism Problem on a Class of Hyperedge Replacement Languages [PDF]
International Conference on Graph Transformation, 2014 A graph class is called A-free if every graph in the class has no graph in the set A as an induced subgraph. Such characterisations by forbidden induced subgraphs are (among other purposes) very useful for determining whether A-free is a subclass of B-free, by determining whether every graph in B has some graph in A as an induced subgraph.

An Efficient Subgraph Isomorphism Solver for Large Graphs
IEEE Access, 2021 For a given pair of pattern and data graphs, the subgraph isomorphism finding problem locates all instances of the pattern graph into the data graph. For a given subgraph isomorphic image of the pattern graph in a data graph, the set of all ordered pairs
