On the Complexity of Rational Verification

no code implementations6 Jul 2022 Julian Gutierrez, Muhammad Najib, Giuseppe Perelli, Michael Wooldridge

To this end, we consider both utilitarian and egalitarian social welfare and show that computing such outcomes is either PSPACE-complete or NP-complete.

Rational Verification for Probabilistic Systems

no code implementations19 Jul 2021 Julian Gutierrez, Lewis Hammond, Anthony W. Lin, Muhammad Najib, Michael Wooldridge

Rational verification is the problem of determining which temporal logic properties will hold in a multi-agent system, under the assumption that agents in the system act rationally, by choosing strategies that collectively form a game-theoretic equilibrium.

Equilibrium Design for Concurrent Games

no code implementations18 Jun 2021 Julian Gutierrez, Muhammad Najib, Giuseppe Perelli, Michael Wooldridge

In particular, we consider system specifications given by LTL and GR(1) formulae, and show that implementing a mechanism to ensure that a given temporal logic property is satisfied on some/every Nash equilibrium of the game, whenever such a mechanism exists, can be done in PSPACE for LTL properties and in NP/$\Sigma^{P}_{2}$ for GR(1) specifications.

Multi-Agent Reinforcement Learning with Temporal Logic Specifications

1 code implementation1 Feb 2021 Lewis Hammond, Alessandro Abate, Julian Gutierrez, Michael Wooldridge

In this paper, we study the problem of learning to satisfy temporal logic specifications with a group of agents in an unknown environment, which may exhibit probabilistic behaviour.

Automated Temporal Equilibrium Analysis: Verification and Synthesis of Multi-Player Games

1 code implementation13 Aug 2020 Julian Gutierrez, Muhammad Najib, Giuseppe Perelli, Michael Wooldridge

In the context of multi-agent systems, the rational verification problem is concerned with checking which temporal logic properties will hold in a system when its constituent agents are assumed to behave rationally and strategically in pursuit of individual objectives.

Equilibria for Games with Combined Qualitative and Quantitative Objectives

no code implementations13 Aug 2020 Julian Gutierrez, Aniello Murano, Giuseppe Perelli, Sasha Rubin, Thomas Steeples, Michael Wooldridge

The overall aim of our research is to develop techniques to reason about the equilibrium properties of multi-agent systems.

Multi-Player Games with LDL Goals over Finite Traces

no code implementations13 Aug 2020 Julian Gutierrez, Giuseppe Perelli, Michael Wooldridge

Linear Dynamic Logic on finite traces LDLf is a powerful logic for reasoning about the behaviour of concurrent and multi-agent systems.
