Large Graph Sampling Algorithm for Frequent Subgraph Mining

open access: yesIEEE Access, 2021
Large graph networks frequently appear in the latest applications. Their graph structures are very large, and the interaction among the vertices makes it difficult to split the structures into separate multiple structures, thus increasing the difficulty ...

Between Subgraph Isomorphism and Maximum Common Subgraph [PDF]

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2017
When a small pattern graph does not occur inside a larger target graph, we can ask how to find "as much of the pattern as possible" inside the target graph. In general, this is known as the maximum common subgraph problem, which is much more computationally challenging in practice than subgraph isomorphism.

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

open access: yesМоделирование 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.

Research on the Top-Down Parsing Method for Context-Sensitive Graph Grammars. [PDF]

open access: yesPLoS ONE, 2015
The parsing problem is one of the key problems of graph grammars. The typical parsing algorithm uses the bottom-up method. The time-complexity of this method is high, and it is difficult to apply.

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.

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 ...
