Dear Colleague,

as you are probably aware of, the upcoming MIC'2001  -  4th
Metaheuristics International Conference to be held in Porto
(Portugal), July 16-20 2001 constitutes one of the main forum for
the scientific community involved in research on metaheuristic
algorithms.

Within the framework of this conference Marco Dorigo and I are
jointly organizing a special session dedicated to Ant Colony
Optimization (ACO). We solicit therefore contributions, in the form
of extended abstracts, describing original research on any aspect of
ACO.

Interested participants should submit a 5/6-page extended abstract in
the following format:

1) a PDF or PS file to both mdorigo@ulb.ac.be and to maniezzo@csr.unibo.it, and
2) one paper copy directly to the MIC'2001 conference organizers.

Deadline for submission is March 12, 2001. Formatting instructions and other
conference related material can be downloaded from the conference web page:

                  CALL FOR PAPERS / CALL FOR PARTICIPATION


                         The IJCAI-01 Workshop on

                       STOCHASTIC SEARCH ALGORITHMS

                       August 6, 2001, Seattle, USA



Workshop Description
=====================

Stochastic search algorithms strongly use randomised decisions while
searching for solutions to a given problem. They play an increasingly
important role for practically solving hard combinatorial problems
from various domains of AI and Operations Research, such as
satisfiability, constraint satisfaction, planning, scheduling, and
many application areas. Over the past few years there has been
considerable success in developing stochastic local search algorithms
as well as randomised systematic search methods for solving these
problems, and to date, for many problem domains, the best known
algorithms are based on stochastic search techniques. The increasing
relevance and popularity of these methods in AI are reflected by a
growing number of publications in journals, such as Artificial
Intelligence and the Journal of Automated Reasoning, and at major AI
conferences, such as IJCAI, ECAI, and AAAI.

This workshop will bring together researchers from different areas of
AI and Operations Research in order to discuss various topics in
stochastic search techniques.


Workshop topics will include:
==============================

-- design and implementation of stochastic search algorithms
-- metaheuristics, learning techniques, and self-tuning algorithms
-- parallelisation and portfolios of stochastic search algorithms
-- empirical analysis and evaluation of stochastic search algorithms
-- theoretical results on stochastic search algorithms
-- stochastic local search vs. randomised systematic search methods
-- new applications of stochastic search

The organisers aim to create a forum for sharing and discussing the
latest results as well as fundamental issues in this highly dynamic
and fast growing area of AI research. This one day workshop is
organised by Holger H. Hoos and Thomas Stuetzle; it is co-ordinated
with the IJCAI-01 Tutorial "Stochastic Search Algorithms" and the
IJCAI-01 Workshop "Empirical Methods in Artificial Intelligence" and
the IJCAI-01 Tutorial "Stochastic Search Algorithms" (also presented /
organised by Holger H. Hoos and Thomas Stuetzle).


Format
=======

This one-day workshop will start with a brief introduction and
overview by the organisers. In 1-2 invited talks, leading experts will
discuss general aspects of stochastic search algorithms and their
application. In addition, selected workshop participants will be
presenting more specific results; these presentations will be selected
based on the technical papers and position statements submitted by the
participants. Issues raised by these presentations will be discussed
by all workshop participants. Furthermore, we are planning to have 1-3
panels (the topics of these panels will be decided based on the
submissions) in which panelists first present their position regarding
possibly controversial issues in a 10 minute exposition.

We will facilitate a workshop atmosphere and promote personal contacts
among the workshop participants by various means. At the start of the
workshop the participants will introduce themselves and give a short
statement on their interest in and experience with stochastic search
algorithms. The panels and general discussions will facilitate
interaction between participants and the sharing of insights and
views. A social programme comprising a joint lunch and dinner will
provide further opportunities for an informal exchange of experiences
and ideas.

This workshop on Empirical Methods in Artificial Intelligence will be
coordinated with the IJCAI-01 Workshop on ``Stochastic Search
Algorithms'' (organised by Holger H. Hoos and Thomas Stuetzle) and the
IJCAI-01 Tutorial on Stochastic Search (held by Holger H. Hoos and
Thomas Stuetzle).


Important Dates
================

  -- Submission deadline:        February 28, 2001
  -- Notification of acceptance: March 25, 2001
  -- Camera-ready copy deadline: April 11, 2001
  -- Workshop:                   August 6, 2001


Submission Procedure
=====================

We ask authors to submit technical papers or position papers either in
Postscript or PDF. Every participant is expected to submit at least a
1-page statement of interest.

Technical papers should address one or more of the workshop
topics. Position papers should describe and justify your view on one
or more topics relevant to this workshop. The paper should be
reasonably concise; technical papers should be in the range from 4 to
6 pages in IJCAI or AAAI conference style, position papers should be
about 1000 words. Submissions should be printed on 8.5" x 11" or A4
paper with at least 1 inch margins on all sides. The first page of the
position paper should include the title, a brief abstract, and author
names, affiliations, postal addresses, electronic mail addresses, and
telephone and fax numbers.

To submit a paper, email it (or a URL pointer to it) to hoos@cs.ubc.ca
and stuetzle@informatik.tu-darmstadt.de.

The number of participants is limited to 40 participants; participants
will be selected based on the submitted position paper. All
participants are expected to contribute to the discussions in the
workshop.

Note that all workshop participants must register for the main
IJCAI-01 conference.
