LAMAS&SR 2022

International Workshop on

Logical Aspects in Multi-Agent Systems and Strategic Reasoning

August 25-26, 2022, Rennes, France
Co-located with AiML 2022
AiML and LAMAS&SR registration

Logics and strategic reasoning play a central role in multi-agent systems. Logics can be used, for instance, to express the agents' abilities, knowledge, and objectives. Strategic reasoning refers to algorithmic methods that allow for developing good behavior for the agents of the system. At the intersection, we find logics that can express existence of strategies or equilibria, and can be used to reason about them.

The LAMAS&SR workshop merges two international workshops: LAMAS (Logical Aspects of Multi-Agent Systems), which focuses on all kinds of logical aspects of multi-agent systems from the perspectives of artificial intelligence, computer science, and game theory, and SR (Strategic Reasoning), devoted to all aspects of strategic reasoning in formal methods and artificial intelligence.

LAMAS: The LAMAS workshop provides a meeting forum for the research community working on various logical aspects of multi-agent systems (MAS) from the perspectives of artificial intelligence, computer science, and game theory. It addresses the whole range of issues that arise in the context of using logic in MAS, from theoretical foundations to algorithmic methods and implemented tools. The workshop LAMAS has been regularly organized since 2002 and became the main annual event of the LAMAS research network.

SR: Strategic reasoning is a key topic in the multi-agent systems research area. The extensive literature in this field includes a number of logics used for reasoning about the strategic abilities of the agents in the system, but spans also game theory, decision theory or epistemic logics to name a few. The aim is to provide sound theoretical foundations and tools to tackle a variety of strategic problems in formal methods and artificial intelligence involving agents in adversarial settings. The workshop SR has been organized every year since 2013, often in co-location with the most important conferences in formal methods and artificial intelligence.

LAMAS&SR: Over the years the communities and research themes of both workshops got closer and closer, with a significant overlap in the participants and organizers of both events. For this reason, the next editions of LAMAS and SR will be unified under the same flag, formally joining the two communities.

About COVID-19

Local organizers are following closely the evolution of the pandemic situation. Our preference is for a full in-person event, but we will employ an online or hybrid format according to the situation.

Call for papers

LAMAS&SR is interested in all topics related to logics and strategic reasoning in multi-agent systems, from theoretical foundations to algorithmic methods and implemented tools. The topics of the workshop include, but are not limited to:

  • Logical systems for specification, analysis, and reasoning about multi-agent systems
  • Logic-based modeling of multi-agent systems
  • Dynamical multi-agent systems
  • Deductive systems and decision procedures for logics for multi-agent systems
  • Development and implementation of methods for formal verification in multi-agent systems
  • Logic-based tools for multi-agent systems
  • Logics for reasoning about strategic abilities
  • Logics for multi-agent mechanism design, verification, and synthesis
  • Logical foundations of decision theory for multi-agent systems
  • Strategic reasoning in formal verification
  • Automata theory for strategy synthesis
  • Applications and tools for cooperative and adversarial reasoning
  • Robust planning and optimization in multi-agent systems
  • Risk and uncertainty in multi-agent systems
  • Quantitative aspects in strategic reasoning

Submissions

Authors are invited to submit extended abstracts of 2 pages plus 1 page for references only, in the AAMAS 2022 format. Both published and unpublished works are welcome. Submissions are subject to a single-blind review process (submissions should not be anonymous).

Although there will be no formal proceedings, accepted extended abstracts will be made available on the workshop website. We envisage that extensions of selected papers will be invited to a special issue.

Authors are invited to submit their manuscript via EasyChair.

Important dates

  • Paper submission: June 5, 2022 (AoE)
  • Author Notification: June 30, 2022 (AoE)
  • Camera Ready: July 15, 2022 (AoE)
  • Workshop: August 25-26, 2022
