Verifying Pushdown Multi-Agent Systems against Strategy Logics

چکیده
In this paper, we investigate model checking algorithms for variants of strategy logic over pushdown multi-agent systems, modeled by pushdown game structures (PGSs). We consider various fragments of strategy logic, i.e., SL[CG], SL[DG], SL[1G] and BSIL. We show that the model checking problems on PGSs for SL[CG], SL[DG] and SL[1G] are 3EXTIME-complete, which are not harder than the problem for the subsumed logic ATL⇤. When BSIL is concerned, the model checking problem becomes 2EXPTIME-complete. Our algorithms are automata-theoretic and based on the saturation technique, which are amenable to implementations.

Global Model Checking on Pushdown Multi-Agent Systems
Pushdown multi-agent systems, modeled by pushdown game structures (PGSs), are an important paradigm of infinite-state multi-agent systems. Alternatingtime temporal logics are well-known specification formalisms for multi-agent systems, where the selective path quantifier is introduced to reason about strategies of agents. In this paper, we investigate model checking algorithms for variants of a...
متن کاملModel Checking Pushdown Epistemic Game Structures
In this paper, we investigate the problem of verifying pushdown multiagent systems with imperfect information. As the formal model, we introduce pushdown epistemic game structures (PEGSs), an extension of pushdown game structures with epistemic accessibility relations (EARs). For the specification, we consider extensions of alternating-time temporal logics with epistemic modalities: ATEL, ATEL∗...
متن کاملVerifying and Synthesising Multi-Agent Systems against One-Goal Strategy Logic Specifications
Strategy Logic (SL) has recently come to the fore as a useful specification language to reason about multi-agent systems. Its one-goal fragment, or SL[1G], is of particular interest as it strictly subsumes widely used logics such as ATL*, while maintaining attractive complexity features. In this paper we put forward an automata-based methodology for verifying and synthesising multi-agent system...
متن کاملModal tableaux for verifying security protocols
To develop theories to specify and reason about various aspects of multi-agent systems, many researchers have proposed the use of modal logics such as belief logics, logics of knowledge, and logics of norms. As multi-agent systems operate in dynamic environments, there is also a need to model the evolution of multi-agent systems through time. In order to introduce a temporal dimension to a beli...
متن کاملA Compilation Method for the Verification of Temporal-Epistemic Properties of Cryptographic Protocols
We present a technique for automatically verifying cryptographic protocols specified in the mainstream specification language CAPSL. Our work is based on model checking multi-agent systems against properties given in AI logics. We present PC2IS, a compiler from CAPSL to ISPL, the input language of MCMAS, a symbolic model checker for MAS. The technique also reduces automatically the state space ...
