扩展参数时间自动机的基准库

A Benchmarks Library for Extended Parametric Timed Automata

Étienne André, Dylan Marinho, Jaco van de Pol

摘要:

参数时间自动机是一个强大的形式化推理的并发实时系统与未知或不确定的时间常数。为了测试新算法的效率,需要一组公平的基准测试。我们提出了一个扩展的IMITATOR基准库,多年来积累了一些案例研究,从学术和工业背景。我们在这里扩展了几十个新的基准库;这些基准突出了几个新的功能:活性属性,(参数)时间自动机(包括秒表或多速率时钟)的扩展,以及不可解的玩具基准。这些后者的补充有助于强调国家的最先进的参数合成技术的限制,希望在未来开发新的专用算法。

英文摘要:

Parametric timed automata are a powerful formalism for reasoning on concurrent real-time systems with unknown or uncertain timing constants. In order to test the efficiency of new algorithms, a fair set of benchmarks is required. We present an extension of the IMITATOR benchmarks library, that accumulated over the years a number of case studies from academic and industrial contexts. We extend here the library with several dozens of new benchmarks; these benchmarks highlight several new features: liveness properties, extensions of (parametric) timed automata (including stopwatches or multi-rate clocks), and unsolvable toy benchmarks. These latter additions help to emphasize the limits of state-of-the-art parameter synthesis techniques, with the hope to develop new dedicated algorithms in the future.
