Yong Li, Wanwei Liu, Andrea Turrini, Ernst Moritz Hahn, Lijun Zhang

摘要:

在本文中,我们提出了一个有效的算法的参数综合PLTL公式的参数关于参数马尔可夫链。将PLTL公式转化为一个几乎完全分块的Büchi自动机,然后将其与参数马尔可夫链组合。然后,我们减少了问题,以解决优化问题,允许决定使用SMT求解器的公式的满意度。该算法也适用于区间马尔可夫链。复杂度在马尔可夫链的大小上是线性的,在公式的大小上是指数的。我们提供了一个原型,并显示了我们的方法的效率在一些基准。

英文摘要:

In this paper, we propose an efficient algorithm for the parameter synthesis of PLTL formulas with respect to parametric Markov chains. The PLTL formula is translated to an almost fully partitioned Büchi automaton which is then composed with the parametric Markov chain. We then reduce the problem to solving an optimisation problem, allowing to decide the satisfaction of the formula using an SMT solver. The algorithm works also for interval Markov chains. The complexity is linear in the size of the Markov chain, and exponential in the size of the formula. We provide a prototype and show the efficiency of our approach on a number of benchmarks.
