Call
----

This workshop invites works from different strands of the multi-agent  
systems community that pertain to the design of algorithms, models,  
and techniques to deal with multi-agent optimisation problems. In so  
doing, this workshop aims to provide a forum for researchers to  
discuss common issues that arise in solving optimisation problems in  
different areas and elaborate common benchmarks to test their solutions.
Note: The authors of the best papers selected from Optmas 2008 and  
2009 will be invited to submit to a special issue of the Journal of  
Autonomous Agents and Multi-Agent Systems  
-http://www.springer.com/computer/artificial/journal/10458  (see below).

********** Invited speaker: Professor Milind Tambe ************
Speaker Bio: Milind Tambe is a Professor of Computer Science at  
University of Southern California(USC). He received his Ph.D. from the  
School of  Computer Science at Carnegie Mellon University. He leads  
the TEAMCORE Research Group at USC, with research interests  in  
multi-agent systems, specifically multi-agent and agent-human  
teamwork. He is a fellow of AAAI (Association for Advancement of  
Artificial Intelligence) and recipient of several awards including ACM  
(Association for Computing Machinery) SIGART Agents Research award.


Background
----------

The number of novel applications of multi-agent systems has followed  
an exponential trend over the last few years, ranging from online  
auction design, through in multi-sensor networks, to scheduling of  
tasks in multi-actor systems. Multi-agent systems designed for all  
these applications generally require some form of optimization in  
order to achieve their goal. Given this, a number of advancements have  
been made in the design of winner determination, coalition formation,  
and distributed constraints optimization algorithms among others.  
However, there are no general principles guiding the design of such  
algorithms that would enable researchers to either exploit solutions  
designed in other areas or to ensure that their algorithms conform to  
some level of applicability to real problems.


This workshop aims to address the above issues by bringing together  
researchers from different parts of the Multi-Agent Systems research  
area to present their work and  discuss acceptable solutions,  
benchmarks, and evaluation methods for generally researched  
optimization problems.

In particular, the main issues to be addressed by the workshop will  
include (but are not limited to):

1. Techniques to model and solve optimisation problems in which the  
actors are partly or completely distributed and can only communicate  
with their peers.

2. Algorithms to compute solutions to mechanisms that deal with  
different stakeholders who may be self interested or may have  
different computation/communication capabilities from their peers.

3. Dealing with privacy concerns: solving complex optimization  
problems while leaking as little private information as possible

4. Problems that require anytime algorithms.

5. Algorithms that need to provide guarantees on the quality of the solution.

6. Mechanisms whose properties can be significantly affected if the  
solution computed is not the optimal one.

7. Techniques to deal with optimizations that have to be repeated with  
possibly only slight changes in the input data.

8. Techniques to deal with situations where the input data may be  
uncertain or unreliable, requiring that the solution computed be  
robust to slight differences from the true values.

9. General heuristics and approximate solutions to multi-agent  
optimisation problems.
