A Logic for Reasoning About Aggregate-Combine Graph Neural Networks

no code implementations30 Apr 2024 Pierre Nunn, Marco Sälzer, François Schwarzentruber, Nicolas Troquard

We also show that a broad class of GNNs can be transformed efficiently into a formula, thus significantly improving upon the literature about the logical expressiveness of GNNs.

Base-based Model Checking for Multi-Agent Only Believing (long version)

no code implementations27 Jul 2023 Tiago de Lima, Emiliano Lorini, François Schwarzentruber

We present a novel semantics for the language of multi-agent only believing exploiting belief bases, and show how to use it for automatically checking formulas of this language and of its dynamic extension with private belief expansion operators.

A Modal Logic for Explaining some Graph Neural Networks

no code implementations11 Jul 2023 Pierre Nunn, François Schwarzentruber

In this paper, we propose a modal logic in which counting modalities appear in linear inequalities.

On simple expectations and observations of intelligent agents: A complexity study

no code implementations5 Jun 2023 Sourav Chakraborty, Avijeet Ghosh, Sujata Ghosh, François Schwarzentruber

Public observation logic (POL) reasons about agent expectations and agent observations in various real world situations.

Epistemic Reasoning

On verifying expectations and observations of intelligent agents

no code implementations2 May 2022 Sourav Chakraborty, Avijeet Ghosh, Sujata Ghosh, François Schwarzentruber

Public observation logic (POL) is a variant of dynamic epistemic logic to reason about agent expectations and agent observations.

Conflict-Based Search for Connected Multi-Agent Path Finding

no code implementations5 Jun 2020 Arthur Queffelec, Ocan Sankur, François Schwarzentruber

We study a variant of the multi-agent path finding problem (MAPF) in which agents are required to remain connected to each other and to a designated base.

Dynamic Epistemic Logic Games with Epistemic Temporal Goals

no code implementations20 Jan 2020 Bastien Maubert, Aniello Murano, Sophie Pinchinat, François Schwarzentruber, Silvia Stranieri

Dynamic Epistemic Logic (DEL) is a logical framework in which one can describe in great detail how actions are perceived by the agents, and how they affect the world.

Reachability and Coverage Planning for Connected Agents: Extended Version

no code implementations11 Mar 2019 Tristan Charrier, Arthur Queffelec, Ocan Sankur, François Schwarzentruber

We study the theoretical complexity of the reachability and the coverage problems of a fleet of connected agents on various classes of topological graphs.

Dynamic Gossip

2 code implementations3 Nov 2015 Hans van Ditmarsch, Jan van Eijck, Pere Pardo, Rahim Ramezanian, François Schwarzentruber

We define six such distributed dynamic gossip protocols, and we characterize them in terms of the topology of the graphs on which they are successful, wherein we distinguish strong success (the protocol always terminates, possibly assuming fair scheduling) from weak success (the protocol sometimes terminates).
