Workshop on Logical Aspects of Multi-Agent Systems (LAMAS 2020)

8-10 May 2020

Welcome

Welcome to the website of the 10th Workshop on Logical Aspects of Multi-Agent Systems (LAMAS 2020). LAMAS 2020 will be a satellite workshop of AAMAS 2020, which will take place May 9-13, 2020 in Auckland, New Zealand. More information on the conference website: https://aamas2020.conference.auckland.ac.nz/

LAMAS 2020 will be the main event of the LAMAS research network and will continue the successful series of LAMAS workshops which includes:

Organization

Because of the covid-19 AAMAS 2020 and associated workshops will be entirely virtual. In order to allow for questions and interaction, which are fundamental aspects of a workshop, we chose to have live presentations. The conference will be held on Zoom.
If you would like the recording of one of the sessions, please write to lamas2020@easychair.org before June 11 2020.

In order to try and make it possible to attend for people on the different continents, the workshop is held over three days: May 8, 9 and 10, at the following time:

May 8:
  • 22:30 - 01:15 New Zealand time
  • 10:30 - 13:15 UTC
May 9 and 10:
  • 22:30 - 00:30 New Zealand time
  • 10:30 - 12:30 UTC

Call for Papers

LAMAS is a scientific network spanning an interdisciplinary community of researchers working on logical aspects of multi-agent systems (MAS) from the perspectives of artificial intelligence, computer science, game theory, and more.

LAMAS2020 will be the next annual event of the LAMAS research network and will continue the series of LAMAS workshops (previous editions were 2002, 2007, 2010, 2011, 2012, 2013, 2014, 2015, 2017). The LAMAS workshop is the pivotal event of the network and it provides a platform for presentation, exchange, and publication of ideas in all these areas, including:

  • Logical systems for modeling, specification, analysis and synthesis of MAS
  • Deductive systems and decision procedures for logics for MAS
  • Algorithmic methods for formal verification of MAS
  • Logic-based tools for MAS
  • Applications of logics in MAS

Submissions

Authors are invited to submit extended abstracts of 2 pages plus 1 page for references in the AAMAS format, reporting their work in one of two categories: either original and unpublished, or published (or accepted for publication) in the last 12 months. Submissions are subject to a single-blind review process (submissions should not be anonymous).

All the accepted papers will appear in the informal workshop proceedings produced together with the AAMAS proceedings. We envisage that extensions of selected papers will be invited to a journal post-proceedings.

Invited Speakers

Giuseppe De Giacomo

BIO: Giuseppe De Giacomo is full professor in Computer Science and Engineering at Univ. Roma “La Sapienza". His research activity has concerned theoretical, methodological and practical aspects in different areas of AI and CS, most prominently Knowledge Representation, Reasoning about Actions, Generalized Planning, Autonomous Agents, Service Composition, Business Process Modeling, Data Management and Integration. He is AAAI Fellow, ACM Fellow, and EurAI Fellow. He is Program Chair of ECAI 2020. He was awarded an ERC Advanced Grant for the project WhiteMech: White-box Self Programming Mechanisms (2019-2024).

Title of the talk: Synthesizing Agent Behaviors in an Environment (i.e., Modern Reasoning about Actions and Planning)

Abstract:

One of the core abilities for an agent is to deliberate how to accomplish a task. This is related to synthesis in Formal Methods, and to reasoning about actions and planning in AI. However one crucial distinction between the two is that in Reasoning about Actions and Planning an agent is equipped with a model of the environment (aka "world", or "domain") where the agent acts in. This distinction is important, since the environment model seldom changes, while the task that the agent has to accomplish changes unceasingly as the agent acts in its environment. We focus on LTL on finite and infinite traces, and discuss how we can generalize the environment models from nondeterministic domains, traditionally used in reasoning about action and planning, to general action theories expressed in LTL, while keeping deliberating about the agent behavior (aka planing or synthesis) manageable.
