An Efficient Index-Based Algorithm for Exact Subgraph Isomorphism on Bipartite Graphs

Scientific Research Communications
Graphs are widely used to represent various real-world networks, but their non-linear nature and size increase pose challenges for efficient analysis. The subgraph isomorphism problem, which involves identifying subgraphs that are isomorphic to a query ...

On the AC0 Complexity of Subgraph Isomorphism

2014 IEEE 55th Annual Symposium on Foundations of Computer Science, 2014
Let P be a fixed graph (hereafter called a "pattern"), and let Subgraph(P) denote the problem of deciding whether a given graph G contains a subgraph isomorphic to P. We are interested in AC0-complexity of this problem, determined by the smallest possible exponent C(P) for which Subgraph(P) possesses bounded-depth circuits of size nC(P)+o(1). Motivated

k-Subgraph Isomorphism on AC0 Circuits [PDF]

open access: possiblecomputational complexity, 2009
Recently, Rossman [STOC '08] established a lower bound of $\omega(n^{k/4})$ on the size of constant-depth circuits for the $k$-clique function on $n$-vertex graphs, which is the first lower bound that does not depend on the depth of circuits in the exponent of $n$. He showed, in fact, a stronger statement: Suppose $f_n:\{0,1\}^{n \choose 2} \rightarrow

Detecting subgraph isomorphism with MapReduce

The Journal of Supercomputing, 2016
In recent years, the MapReduce framework has become one of the most popular parallel computing platforms for processing big data. MapReduce is used by companies such as Facebook, IBM, and Google to process or analyze massive data sets. Since the approach is frequently used for industrial solutions, the algorithms based on the MapReduce framework gained

Heuristic sampling for the subgraph isomorphism problem [PDF]

open access: possible2017 IEEE 14th International Scientific Conference on Informatics, 2017
Subgraph isomorphism is one of the fundamental search problems in computer science. In this article we consider the counting variation of this problem. The task is to count all instances of the pattern G occurring in a (usually larger) graph H. All algorithms for this problem use a variation of backtracking. Most commonly they assign one vertex of G to

Inexact subgraph isomorphism in MapReduce

Journal of Parallel and Distributed Computing, 2013
Inexact subgraph matching based on type-isomorphism was introduced by Berry et al. [J. Berry, B. Hendrickson, S. Kahan, P. Konecny, Software and algorithms for graph queries on multithreaded architectures, in: Proc. IEEE International Parallel and Distributed Computing Symposium, IEEE, 2007, pp.

Isomorphic edge disjoint subgraphs of hypergraphs

Random Structures & Algorithms, 2016
We show that any k-uniform hypergraph with n edges contains two isomorphic edge disjoint subgraphs of size for k = 4, 5 and 6. This is best possible up to a logarithmic factor due to an upper bound construction of Erdős, Pach, and Pyber who show there exist k-uniform hypergraphs with n edges and with no two edge disjoint isomorphic subgraphs with size ...
