		*** The First CLIMA Contest ***

Organised by Jürgen Dix, Technical University of Clausthal, and Mehdi
Dastani, Utrecht University


Multi-agent systems are beginning to play an important role in today’s
software development. See for example the forthcoming new International
Journal of Agent-Oriented Software Engineering

This competition is an attempt to stimulate research in the area of
multi-agent systems by

    * identifying key problems and
    * collecting suitable benchmarks

that can serve as milestones for testing new approaches and techniques
from computational logics. While there exist several competitions in
various parts of artificial intelligence (theorem proving, planning,
robo-cup etc) and, lately, also in specialised areas in agent systems
(trading agents), the emphasis of this contest is on the use of
'computational logic' in (multi-) agent systems.

We expect to promote the development of multi-agent systems by first
identifying difficult problems and then finding solutions by comparing
different approaches from computational logic for solving them. While
this idea seems very appealing, it is not an easy task to come up with a
particular scenario that serves as a basis for a contest. Such a
scenario should be generic enough to be applicable for a wide range of
techniques of computational logic, but it should also be precise enough
so that different approaches can be tested and compared against each

* Scenario description

This competition is organised as part of CLIMA and consists of
developing multi-agent systems to solve a cooperative task in a
dynamically changing environment. The environment of the multi-agent
system is a grid-like world where agents can move from one slot to a
neighbouring slot if there is no agent already in that slot. In this
environment, food can appear in all but one of these slots. The special
slot, in which no food can appear, is considered as a depot where the
agents can bring and collect their food. An agent can observe if there
is food in the slot it is currently visiting. Initially, food can be
placed in some randomly selected slots. During the execution, additional
food can appear dynamically in randomly selected slots except the depot
slot. The agents may have/play different roles (such as explorer or
collector), communicate and cooperate in order to find and collect food
in an efficient and effective way.

We encourage submissions that specify and design a multi-agent system in
terms of high-level concepts such as goals, beliefs, plans, roles,
communication, coordination, negotiation, and dialogue in order to
generate an efficient and effective solution for the above mentioned
application. Moreover, the multi-agent system implementations should be
based on computational logic techniques (e.g. logic programming, formal
calculi, etc) and they should reflect their design in a direct and
intuitive way.

The challenge of this competition is thus to use computational logic
techniques to provide implemented models for the abstract concepts that
are used in the specification and design of multi-agent systems. These
implemented models should be integrated to implement the above-mentioned
application intuitively, directly, and effectively.
Submission format

* A submission consists of two parts.

The first part is a description of analysis, design and implementation
of a multi-agent system for the above application. Existing multi-agent
system methodologies such as Gaia, Prometheus and Tropos can be used
(not demanded) to describe the analysis and design of the system. For
the description of the implementation, it should be explained how the
design is implemented. This can be done by explaining, for example,
which computational logic techniques are used to implement certain
aspects of the multi-agent system (including issues related to
individual agents). The maximum length of this description is 5 pages
according to the LNCS format.

The second part is an (executable) implementation of the application. We
do not demand any particular way (data format, algorithm, mechanism) to
implement the system as long as it is implemented as a multi-agent
system and as long as the environment is a 20x20 grid. Moreover, it
should be possible to configure the initial state of the environment to
place food in arbitrary slots. During the execution food should appear
automatically every 20 seconds in a randomly selected slot. The
multi-agent system will be run with 4 agents that are positioned
initially at the corners of the grid. The implementation should be
executable on a windows or linux machine.
How To Submit

Please follow this link to register and submit the 5 page description of
your solution. You can then submit the implementation by e-mail (to the
CLIMA Contest Chairs) or by specifying in your paper a URL where the
implementation can be downloaded from. In the registration, please
select 'Competition' in the paper type (tracks) drop-down menu.
Winning Criteria

The criteria that will be used to evaluate submission and to select the
first three winners are as follows:

   1. Original, innovative, and effective application of computational
logic techniques in solving specific multi-agent issues identified in
this application.
   2. The performance of the executable implementation. The performance
of the executable implementation will be measured based on the amount of
food that is collected by the multi-agent system in a certain period of
time. All programs will be run on the same machine (Windows/Linux double
boot machine).
   3. The quality of the description of analysis, design and
implementation of the multi-agent system, the elegance of its design and
implementation, and the ease of installation and execution of the
