On isomorphic subgraphs

open access: yesDiscrete Mathematics, 1993
This note is concerned with a question on the maximum possible \(s\) such that an arbitrary graph or hypergraph \(G\) contains a pair of edge disjoint isomorphic subgraphs of size \(s\). The authors investigate this question in the case of 3-uniform hypergraphs.

Filtering for subgraph isomorphism [PDF]

open access: yes, 2007
A subgraph isomorphism problem consists in deciding if there exists a copy of a pattern graph in a target graph. We introduce in this paper a filtering algorithm dedicated to this problem. The main idea is to label every node with respect to its relationships with other nodes of the graph, and to define a partial order on these labels in order to ...

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.

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

open access: yesИзвестия Саратовского университета. Новая 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 ...

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 ...

GSI: GPU-friendly Subgraph Isomorphism [PDF]

open access: yes2020 IEEE 36th International Conference on Data Engineering (ICDE), 2020
Subgraph isomorphism is a well-known NP-hard problem that is widely used in many applications, such as social network analysis and query over the knowledge graph. Due to the inherent hardness, its performance is often a bottleneck in various real-world applications.

An Algorithm for Subgraph Isomorphism [PDF]

open access: yesJournal of the ACM, 1976
Subgraph isomorphism can be determined by means of a brute-force tree-search enumeration procedure. In this paper a new algorithm is introduced that attains efficiency by inferentially eliminating successor nodes in the tree search. To assess the time actually taken by the new algorithm, subgraph isomorphism, clique detection, graph isomorphism, and ...

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.
