Abstract

Abstract In this paper, we study a well-known computationally hard problem, called the subgraph isomorphism problem where the goal is for a given pattern and target graphs to determine whether the pattern is a subgraph of the target graph. Numerous algorithms for solving the problem exist in the literature and most of them are based on the backtracking approach. Since straightforward backtracking is usually slow, many algorithmic refinement techniques are used in practical algorithms. The main goal of this paper is to study such refinement techniques and to determine their ability to speed up backtracking algorithms. To do this we use a methodology of experimental algorithmics. We perform an experimental evaluation of the techniques and their combinations and, hence, demonstrate their usefulness in practice.

子图同构回溯算法改进技术的实验评价

摘要本文研究了子图同构问题，该问题的目标是给定的模式和目标图是否为目标图的子图。文献中存在许多求解该问题的算法，其中大多数都是基于回溯方法。由于直接回溯通常很慢，因此在实际算法中使用了许多算法改进技术。本文的主要目标是研究这种细化技术，并确定它们加速回溯算法的能力。为了做到这一点，我们使用实验算法的方法。我们对这些技术及其组合进行了实验评估，从而证明了它们在实践中的实用性。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
