摘要:
我们研究了在图中受上下文无关文法约束的可达性问题,重点在于复杂性和实证性能。我们提出了一种用于评估受上下文无关文法约束的可达性查询的算法框架,并分析其理论运行时间界限。为了补充我们的理论结果,我们在全面的现实世界模式基准上进行了广泛的实证评估,比较了不同的算法变体,并报告了性能权衡。我们的结果突显了文法结构和图特性对可达性计算的影响,并为实际选择高效方法提供了指导。
英文摘要:
We study the problem of grammar-constrained context-free language reachability in graphs, focusing on complexity and empirical performance. We present an algorithmic framework for evaluating reachability queries constrained by context-free grammars, and analyze its theoretical runtime bounds. To complement our theoretical results, we conduct an extensive empirical evaluation on a comprehensive benchmark of real-world schemas, comparing different algorithmic variants and reporting performance trade-offs. Our results highlight the impact of grammar structure and graph characteristics on reachability computation, and provide guidance for selecting efficient approaches in practice.
