Everything you always wanted to know about the parameterized complexity of Subgraph Isomorphism (but were afraid to ask) [PDF]
Given two graphs H and G, the Subgraph Isomorphism problem asks if H is isomorphic to a subgraph of G. While NP-hard in general, algorithms exist for various parameterized versions of the problem.

On the First-Order Complexity of Induced Subgraph Isomorphism [PDF]
Given a graph $F$, let $I(F)$ be the class of graphs containing $F$ as an induced subgraph. Let $W[F]$ denote the minimum $k$ such that $I(F)$ is definable in $k$-variable first-order logic.

Faster Algorithms for the Maximum Common Subtree Isomorphism Problem [PDF]
The maximum common subtree isomorphism problem asks for the largest possible isomorphism between subtrees of two given input trees. This problem is a natural restriction of the maximum common subgraph problem, which is ${\sf NP}$-hard in general graphs ...

Subgraph Query for Building Service-Based Systems
Given the broad applications of service-oriented architecture (SOA) in service-oriented software engineering, service-based systems (SBSs) built from existing Web services are becoming increasingly popular.

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

Efficient Algorithms for Subgraph Listing
Subgraph isomorphism is a fundamental problem in graph theory. In this paper we focus on listing subgraphs isomorphic to a given pattern graph. First, we look at the algorithm due to Chiba and Nishizeki for listing complete subgraphs of fixed size, and ...

The resource scheduling problem of UAV communication networks has always been a hot research issue in the current environment. However, most of the current research focuses on meeting the user’s time cost requirements and rarely considers the user’s ...

Quantum Query Complexity of Subgraph Isomorphism and Homomorphism [PDF]
Let $H$ be a fixed graph on $n$ vertices. Let $f_H(G) = 1$ iff the input graph $G$ on $n$ vertices contains $H$ as a (not necessarily induced) subgraph. Let $\alpha_H$ denote the cardinality of a maximum independent set of $H$. In this paper we show: \[

Maximum common subgraph isomorphism algorithms for the matching of chemical structures [PDF]
The maximum common subgraph (MCS) problem has become increasingly important in those aspects of chemoinformatics that involve the matching of 2D or 3D chemical structures. This paper provides a classification and a review of the many MCS algorithms, both

GC : a graph caching system for subgraph / supergraph queries [PDF]
We demonstrate a graph caching system GC for expediting subgraph/supergraph queries, which are computationally expensive due to the entailed NP-Complete subgraph isomorphism problem.
