Abstract
It is well known that the verification of resource-constrained multi-agent systems is undecidable in general. In many such settings, resources are private to agents. In this paper, we investigate the model checking problem for a resource logic based on Alternating-Time Temporal Logic (ATL) with shared resources. Resources can be consumed and produced up to any amount. We show that the model checking problem is undecidable if two or more of such unbounded resources are available. Our main technical result is that in the case of a single shared resource, the problem becomes decidable. Although intuitive, the proof of decidability is non-trivial. We reduce model checking to a problem over alternating Büchi pushdown systems. An intermediate result connects to general automata-based verification: we show that model checking Computation Tree Logic (CTL) over (compact) alternating Büchi pushdown systems is decidable.
