概率系统的模型检测问题主要依赖于将LTL转换为确定性Rabin自动机（DRW）。我们最近的Safraless翻译[KE12，GKE12]的LTL（F，G）片段产生较小的自动机相比，传统的方法。在这项工作中，而不是DRW，我们认为确定性自动机的接受条件作为广义拉宾对（DGRW）的析取。与DRW相比，LTL（F，G）公式到DGRW的Safraless翻译导致更小的自动机。我们提出了概率模型检测算法以及DGRW条件下的博弈求解。我们的新算法在理论界和实际评价方面都有所改进。我们比较PRISM与我们的新的翻译，并表明，新的翻译导致显着的改善。
The model-checking problem for probabilistic systems crucially relies on the translation of LTL to deterministic Rabin automata (DRW). Our recent Safraless translation [KE12, GKE12] for the LTL(F,G) fragment produces smaller automata as compared to the traditional approach. In this work, instead of DRW we consider deterministic automata with acceptance condition given as disjunction of generalized Rabin pairs (DGRW). The Safraless translation of LTL(F,G) formulas to DGRW results in smaller automata as compared to DRW. We present algorithms for probabilistic model-checking as well as game solving for DGRW conditions. Our new algorithms lead to improvement both in terms of theoretical bounds as well as practical evaluation. We compare PRISM with and without our new translation, and show that the new translation leads to significant improvements.
