Node Embedding and Cosine Similarity for Efficient Maximum Common Subgraph Discovery

open access: yesApplied Sciences
Finding the maximum common induced subgraph is a fundamental problem in computer science. Proven to be NP-hard in the 1970s, it has, nowadays, countless applications that still motivate the search for efficient algorithms and practical heuristics.

Maximum Common Subgraph Isomorphism Algorithms [PDF]

open access: yes, 2017
Maximum common subgraph (MCS) isomorphism algorithms play an important role in chemoinformatics by providing an effective mechanism for the alignment of pairs of chemical structures. This article discusses the various types of MCS that can be identified

Topological features and iterative node elimination for speeding up subgraph isomorphism detection

open access: yes, 2023
In this paper we tackle the problem of subgraph isomorphism detection on large graphs, which may commonly be intractable, even with state of the art algorithms. Rather than competing with other matching algorithms, we define enhancements that can be used

The Formula Complexity of Subgraph Isomorphism

open access: yes, 2017
I will report recent progress on the formula complexity of the (colorful) subgraph isomorphism problem. (1) In previous work with Li and Razborov (FOCS 2014), we showed that the AC0-circuit complexity of G-subgraph isomorphism is n^{Theta~(treewidth(G))

Random Generation Topology Coding Technique in Asymmetric Topology Encryption

open access: yesMathematics
The security of traditional public key cryptography algorithms depends on the difficulty of the underlying mathematical problems. Asymmetric topological encryption is a graph-dependent encryption algorithm produced to resist attacks by quantum computers ...

Subgraph isomorphism problem in planar graphs

open access: yes, 2013
V problemu izomorfizma podgrafov imamo podana dva grafa G in H. Za njiju je potrebno ugotoviti, ali graf G vsebuje podgraf, ki je izomorfen grafu H. Problem je v splošnem NP-poln. V magistrskem delu se omejimo na problem izomorfizmov podgrafov ravninskih

Inductive queries for a drug designing robot scientist

open access: yes, 2010
It is increasingly clear that machine learning algorithms need to be integrated in an iterative scientific discovery loop, in which data is queried repeatedly by means of inductive queries and where the computer provides guidance to the experiments that ...

Fast and Accurate Efficient Streaming Subgraph Isomorphism

open access: yes
Queries to detect isomorphic subgraphs are important in graph-based data management. While the problem of subgraph isomorphism search has received considerable attention for the static setting of a single query, or a batch thereof, existing approaches do

cuTS: Scaling Subgraph Isomorphism on Distributed Multi-GPU Systems Using Trie Based Data Structure

open access: yes, 2021
Subgraph isomorphism is a pattern-matching algorithm widely used in many domains such as chem-informatics, bioinformatics, databases, and social network analysis. It is computationally expensive and is a proven NP-hard problem. The massive parallelism in
