REPORT FROM THE ASSOCIATION FOR CONSTRAINT PROGRAMMING

This is a short summary of activities within the ACP during the months April-June 2010.

The 2010 ACP Executive Committee comprises the following people:

  • Barry O'Sullivan - President
  • Jimmy H.M. Lee - Secretary (non-elected)
  • Thomas Schiex - Treasurer
  • Pedro Meseguer - Conference Coordinator
  • John Hooker
  • Karen Petrie
  • Peter Stuckey
  • Roland Yap

ACP.1. ACP Executive Committee Elections 2010

As set out in the new by-laws there will be elections for four new EC members in 2010. Karen Petrie and Roland Yap were elected to two year terms ending in 2010. Pedro Meseguer and Thomas Schiex were elected to three year terms ending in 2010. As set out in the bylaws an Election Committee has been formed chaired by Jimmy Lee. Nominations for candidates will be managed by that committee. Members of the association can nominate candidates. The committee will also proactively seek nominations. The formal text of the call for nominations is being circulated.

The remaining members of the current EC are John Hooker, Barry O'Sullivan, and Peter Stuckey. Their elected terms come to an end in 2012.

ACP.2. ACP Doctoral Research Award 2010

A strong field of nominations has been received for the ACP Doctoral Research Award. A committee established by the EC is responsible for selecting the winning candidate for this award. Members from the general community are recruited to serve as reviewers and make recommendations on the overall winner.

ACP.3. New Award: the ACP Outstanding Service Award

A strong field of nominations has been received for this new award, which we plan to give at CP 2010. At present the EC is working on the selection of the first recepient. This award is to be given to an individual who has made significant contributions to the ACP community in a service capacity. Like the two existing awards, nominations were sought from the community.

ACP.4. Reminder: CP Conference in 2011

The ACP-EC would like to remind members that CP-2011 will be held in Perugia in Italy. The Conference Chair will be Stefano Bistarelli. The Programme Chair for CP-2011 will be announced shortly.

ACP.5. ACP Summer School 2010

This year's summer school was held from the 3rd-7th May in Aussois, France, organized by Y. Deville and C. Solnon. There were over 50 participants. The program included both introductory courses on the grounds of CP, with practicals with the Comet programming language, and advanced courses on challenging research areas of CP. The speakers were Yves Deville, Pierre Flener, Christophe Lecoutre, Laurent Michel, Gilles Pesant, Jean- Charles Régin, Thomas Schiex, Christine Solnon, and Pascal Van Hentenryck.

On behalf of the ACP, the EC would like to thank the speakers and tutorialists, and sincerely congratulate Christine and Yves for organising such a wonderful event.

ACP.6. CP 2010 in St. Andrews, Scotland

The ACP EC would like to extend an invitation to all members of the CP community to attend the CP 2010 conference in St. Andrews. A sincere thanks goes to Dave Cohen, whose job as PC Chair has taken much of his time recently as he finalised the list of accepted papers. We wish Karen Petrie, Conference Chair, and her team every success as they prepare for the conference in September (6th-10th).

Book: - Ant Colony Optimization and Constraint Programming

April 2010, Wiley-ISTE

Ant Colony Optimization (ACO) is a metaheuristic which has been successfully applied to a wide range of combinatorial optimization problems. This book describes ACO and studies its efficiency for solving hard combinatorial problems, with a specific focus on constraint programming. The text is organized into three parts.

The first part introduces constraint programming, which provides high level features to declaratively model problems by means of constraints. It describes the main existing approaches for solving constraint satisfaction problems, including complete tree search approaches, local search and metaheuristics, and shows how they can be integrated within constraint programming languages.

The second part describes the ant colony optimization metaheuristic. Beyond the ant metaphor, it describes the mechanisms which allow artificial ants to converge towards solutions and, more particularly, those used to balance diversification and intensification.

The third part illustratesACO on different constraint satisfaction problems, and shows how to integrate ACO into a constraint programming library, thus combining the expressive power of constraint programming languages, to describe problems in a declarative way, and the solving power of ACO, to efficiently solve these problems.

Career news

Microsoft Research PhD Scholarship 2011

The MSR PhD Scholarship program starts again. You'll find all the details here, http://research.microsoft.com/en-us/collaboration/global/apply-europe.aspx

Application deadline 15 September 2010.

Two postdoc positions in Optimization and Sustainable Development (Microsoft-CNRS Chair, LIX Ecole Polytechnique)

The Microsoft Research-CNRS chair "Optimization for Sustainable Development" (http://chaire-osd.polytechnique.fr/) at LIX, Ecole Polytechnique (near Paris, France) is inviting applications for two postdoctoral positions in the field of Operations Research applied to Sustainable Development applications.

Research at the OSD Chair focuses on the use of optimization techniques to applications in sustainable development, including transportation, scheduling and energy-related topics. Methodology-wise, we pursue interests in: multi-objective optimization, stochastic programming, combinatorial optimization, nonlinear and mixed-integer programming.

Current projects carried out by Chair members focus on:

  • green VRP
  • multi-modal shortest paths in dynamic road networks
  • multi-objective shortest paths
  • solution algorithms for mixed-integer nonlinear programming
  • graph theory and combinatorial optimization
Applicants must hold a Ph.D. in an optimization related field, and have an interest in applications to sustainable development.

Applications should include:

  • a motivation letter
  • a detailed CV (including a complete list of publications)
  • two reference letters
  • a research statement detailing the proposed research field
Application material should be sent to Leo Liberti (leoliberti@gmail.com) and carry "OSD chair postdoc" in the subject field. The deadline for applications is July 15, 2010, with a view to start around October 2010.

One of the two positions concerns the Multiobjective Optimization project described below. The other position is open (preferably within one of the research subjects listed above).

Multiobjective optimization (MOO) problems with preferences are MOO problems plus preferences over the objectives. Therefore preferences act as a filter and select the "preferred" solutions among Pareto-optimal ones. Preferences can be incorporated in MOO at different levels: before resolution, during the search process or after the resolution process.

On the other hand, representing and reasoning about/with preferences have been extensively developed in Artificial Intelligence over the past decade resulting in robust and successful languages for preferences representation. The aim of this project is to integrate these languages into MOO problems.

Applicants to the "MOO&Preferences" project should specify their preference *clearly* in their application. Limited to the MOO applicants, knowledge of theory of preferences, multicriteria optimization, stochastic programming is a plus. Applications specific to the MOO project should be sent to Souhila Kaci (kaci@cril.fr). The deadline for applications is July 15, 2010, with a view to start around October 2010.

Post-Doc Positions at Univ. College Dublin

The Complex and Adaptive Systems Laboratory at University College Dublin is opening three post-doctoral positions in the area of Boolean-based constraint solving and optimization. The post-doctoral researchers will be involved in developing new decision and optimization procedures for Satisfiability Modulo Theories (SMT) and Boolean Satisfiability (SAT).

Applicants should have a PhD degree in Computer Science or related discipline. Experience with tool development is desirable. The post-doctoral researcher appointments will be for either 1 or 3 years. The salary for post-doctoral researchers varies between 37750 EUR and 46255 EUR, depending on experience.

More information is available at http://www.csi.ucd.ie/staff/jpms/vacancies/ and at http://www.ucd.ie/hr/jobvacancies/. The deadline for applications is June 11. Informal enquiries should be directed to Joao Marques-Silva (http://www.csi.ucd.ie/staff/jpms/).

Post Graduate position in Risk Management at University College Cork, Ireland

STOCHASTIC CONSTRAINT PROGRAMMING FOR MINIMISING RISK

Stochastic Programming is a subfield of Operations Research that can solve multi-stage decision problems. Constraint Programming is a younger subfield of Artificial Intelligence aimed at deterministic (non-stochastic) problems, with a rich modelling language and a large family of powerful solution algorithms. Stochastic Constraint Programming (SCP) is a recent hybrid of the two frameworks, designed to compactly model and efficiently solve problems involving both constraints and uncertainty. However, SCP requires further development in order to be a useful real-world tool, as most current solution algorithms do not scale up to large applications.

This project will develop SCP for risk management. It is part of a project jointly funded by the Irish Research Council for Science and Engineering Technology (IRCSET) and IBM. Three different strands will work alongside IBM in carrying out new research to make users better informed about risk, through a wide variety of mathematical and AI instruments. Its overarching objective is to bring together complementary approaches to risk assessment and delivery.

Principal Investigator: Dr S. Prestwich (s.prestwich@cs.ucc.ie)

The candidate should have (or be about to obtain) a good honours degree in Computer Science, Artificial Intelligence, Operations Research or a related subject.

Professorship in Constraint Programming

University College Cork (UCC) occupies a unique place in the history of Computer Science and Information Technology - Boolean algebra, one of the fundamental ideas underlying the design of both computer hardware and software, was developed by George Boole, who was a professor of Mathematics in the University.

Today, Computer Science, which is part of the College of Science, Engineering and Food Science, is one of the largest academic units within the University. There are about 450 undergraduate students, 100 students following taught post-graduate programmes and 45 research students, the vast majority at doctoral level. There are 30 academic and 13 support staff. In addition, 32 post-doctoral researchers are employed in the various research groups and centres within Computer Science.

Applications are invited for the above full-time permanent post.

The person appointed will be expected, if asked to do so, to serve as Director of the Cork Constraint Computation Centre (4C), the largest research group in Computer Science. Staff in 4C comprise 8 academic staff, 22 research staff and 9 support staff; there are 21 research students, the majority at doctoral level.

The appointee will have a doctorate in Computer Science or a related discipline; a scholarly and research reputation of international standing in Constraint Programming or a closely-related field, with a significant record of sustained internationally published research; and a proven track record of seeking and obtaining substantial funding for research. A strong record of engagement with industry will be an advantage.

UCC is committed to supporting its regional hinterland by engaging in world-class research and education, with a diversified, international university community. In line with this, Computer Science wishes to strengthen its strategic capabilities at senior level to support the continuing development of its teaching, research and publication activities.

Postdoctoral Position in Symbolic Computation

The INRIA Cassis team in Besançon, France, is offering a half-year post-doctoral position on the formalization of multi-scale methods for MEMS arrays.

The context is the design of microsystem array architectures, including microcantilevers, micromirrors, droplet ejectors, micromembranes, microresistors, biochips, etc to cite only a few. The numerical simulation of such whole arrays based on classical methods like the Finite Element Method (FEM) is prohibitive for today's computers (at least in a time compatible with the time scale of a designer). The calculation of a reasonably complex cell of a three-dimensional microsystem requires about 1000 degrees of freedoms which leads to about 10 000 000 degrees of freedoms for a 100 x 100 array. There is a solution consisting in approximating the model by a multi-scale method. The resulting approximated model is rigorously derived from the exact one through a sequence of formal transformations that differs for each case. A great challenge is to generalize these formal computations and to automate them, at least in part. The post-doctoral work consists in prototyping the implementation of a family of formal transformations used in multiscale methods, in a computer algebra system (e.g. Maple, the symbolic toolbox of Matlab, or Sage) and to validate them by comparison with hand-made derivations described in the literature on this subject.

Candidates are expected to have a strong background in formal methods. A good mathematical background would be appreciated.

Applicants should submit a curriculum vitae, their Ph.D. dissertation, a statement of research, and recommendation letters. Applications should be received as soon as possible and before June 8, 2010, date of a first selection, although the search will continue until an appropriate candidate has been identified.

Informal inquiries about the position should be directed to Alain Giorgetti (alain.giorgetti@univ-fcomte.fr).

It would be highly appreciated if you could share this announcement with your colleagues, students and individuals whose research is in computer science, computer engineering, and related areas.

Post-doctoral position "Distributed constraint reasoning for virtual power plant" in Mines de Douai

Context
The liberalization of electricity market and the massive introduction of Distributed Generation (DG) (wind turbine, photovoltaic panels, micro turbine generators...) induce many issues in the power management system of electrical networks. Currently, all management tasks of a power grid (operation, optimization, planning and supervision) are performed through a central process. Recent researches have investigated the use of multi-agent systems in power grids.

Subject
This post-doctoral position aims to study the benefits of multi-agent systems for a large-scale deployment of many small DGs and their integration in a virtual power plant. More precisely, the candidate will develop multi-agent coordination mechanisms based on distributed constraint reasoning (DCR). DCR provides a promising framework to deal with distributed real-world problems involving variables and constraints shared by different agents. DisCSP / DCOP models will be developped in collaboration with partners working on the electrical engineering part of the project.

Skills and qualifications
Candidates should have a PhD in multi-agent systems and / or constraint reasoning. Experiences with disCSP / DCOP solving is expected. Experiences in Electrical Engineering would be appreciated.

The position will be for a period of 18 months starting from september 2010, located in Douai, France. The salary will depend on qualifications and experience.

Candidates are invited to send as soon as possible, a CV and a covering letter to: arnaud.doniec@mines-douai.fr and stephane.lecoeuche@mines-douai.fr
