约束系统上时态逻辑的有界可达性

Bounded Reachability for Temporal Logic over Constraint Systems

Marcello M. Bersani, Achille Frigeri, Angelo Morzenti, Matteo Pradella, Matteo Rossi, Pierluigi San Pietro

摘要:

我们提出了CLTLB(D),一个扩展PLTLB(PLTL与过去和未来的运营商)增加了原子公式建立在一个约束系统D。即使对于可判定的约束系统,这种逻辑的可满足性和模型检验问题也可能是不可判定的。我们引入适当的限制和假设,使扩展逻辑可判定的可满足性问题。此外,对于一个大类的约束系统,我们提出了一个编码,实现了一个有效的决策过程的有界可达性问题。

英文摘要:

We present CLTLB(D), an extension of PLTLB (PLTL with both past and future operators) augmented with atomic formulae built over a constraint system D. Even for decidable constraint systems, satisfiability and Model Checking problem of such logic can be undecidable. We introduce suitable restrictions and assumptions that are shown to make the satisfiability problem for the extended logic decidable. Moreover for a large class of constraint systems we propose an encoding that realize an effective decision procedure for the Bounded Reachability problem.
