Welcome to CP News, an initiative of the Association for Constraint Programming.

We aim to provide a comprehensive summary of important news in the area of constraint programming. The newsletter is published quarterly in January, April, July, and October. Please email the relevant editor with any news, event, report or profile you want published. To subscribe, please register here.

* Association for Constraint Programming (ACP)

          ACP EC news: October 1st to December 31th, 2006


This is a short summary of the activities of the ACP EC during the months October-December 2006.

* Appointment for all the EC charges.

All the charges of the ACP (president, vice-president, secretary, treasurer and conference coordinator) were reconsidered. After an internal election process, with the following candidates:

-President: Francesca Rossi, Jean-Charles Régin

-Vice-president: Peter van Beek, Frédéric Benhamou

-Secretary: Pedro Meseguer

-Treasurer: Christian Bessiere

-Conference coordinator: Barry O'Sullivan

the following people were elected:

-President: Francesca Rossi

-Vice-president: Peter van Beek

-Secretary: Pedro Meseguer

-Treasurer: Christian Bessiere

-Conference coordinator: Barry O'Sullivan

These charges will be held for one year (until CP 2007).

* Discussion on possible changes in the ACP rules.

The EC is considering the possibility to improve some of the ACP rules. To do this, a subcommittee of the EC, chaired by Michael Trick, is analyzing many other associations and is discussing possible improvements of the current set of ACP rules. The whole ACP EC will then decide on the changes, which will apply within a year.

* Feedback on Doctoral Program.

A procedure  has been activated to get feedback from students that have participated in the Doctoral Program of previous conferences. This information will be used to improve the structure of the DP in future CP conferences.

* Decision for 2007 CP summer school.

The call for bids for the CP 2007 summer school was sent out soon after CP 2006, and it has been closed on December 20. The ACP EC decided to accept the bid prepared by Javier Larrosa and Pedro Meseguer, who will organize the 2007 CP Summer School in Spain (in some place by the coast near Barcelona) in June 2007. It will be a general school, with lectures on various aspects of CP. More details will be posted soon.


Please visit the website  of the Association, http://www.a4cp.org/. It explains the purpose  of the ACP and its rules,  and it provides links to the ACP EC elections, the Constraints Journal,  the CP conferences, the CP summer school, the  Yahoo! discussion group on constraints, and other activities of the ACP.

* We are saddened to pass on news that Marco Cadoli (http://www.dis.uniroma1.it/~cadoli ) has passed away on November 21, 2006, after a long battle with cancer. He leaves his beloved wife Laura and two small sons Andrea and Riccardo. Marco made many contributions to research in constraints, satisfiability, knowledge representation and databases. An international symposium in Rome is being planned in his honour, just before the next Italian AI Conference.

Summary : Constraint Programming is a powerful tool for solving problems in AI and for Decision Support Systems.  Two aspects are important: the modelling language has to be expressive and the solver efficient.

Our contributions tackle these two problems.  We propose automatic solver construction techniques based on Machine Learning for an arbitrary constraint defined in extension. These techniques yield different filtering levels.  When a concept known only by a subset of positive and negative examples has to be used as a constraint in a problem, we propose a technique to learn the constraint and derive from this step a propagator.

Then, we have studied the problem of quantified constraints which is able to model uncertainty or competition against an opponent.  We have proposed and built a solver for an extended language which is able to express naturally quantified problems and at the same time to solve them faster.

* Brice Pajot, Phd Thesis : Modèles et architectures pour la résolution coopérative par

solveurs de contraintes (in french) http://login.irin.sciences.univ-nantes.fr/thesis-private

Abstract :

The research area of this thesis is related to (cooperative) constraint solving –(C)CS. Classical CS methods yield generally poor performances on large scale problems. New methods are oriented towards synergetic behaviours. The literature brings numerous examples of successes associated to the combination (in the large sense) of CS techniques. Solver cooperation - SC- is related to these problematics. While ad-hoc combination methods are widespread, works on frameworks which enhance the definition and reuse of these assemblies are clearly more sporadic. SC is at the crossway of various problematics including software components or coordination; moreover, it is also close to fields like web services and distributed computing tools, which enhance the modularity, the genericity and the efficiency of related frameworks. The work of this thesis first tries to clarify the different approaches while extracting the shared concepts. We then try to integrate them in an homogeneous framework, where on the one hand, we try to promote  reusability, while on the other, common interactions are reproducable. Besides this conceptual work at the so-called models level, we will present various propositions related to architecture and domain specific language implementations. The latter mainly benefit from the experience acquired in the European project coconut, which aimed at improving the performances of the best known solving methods for continuous guaranteed global optimisation problems using CCS.


* Tony Lambert, PhD Thesis : Hybridation de méthodes complètes et incomplètes pour la résolution de CSP (in french) http://www.info.univ-angers.fr/pub/lambert/these_Tony_Lambert.pdf

Hybridization of complet and incomplete methods to solve CSP

Hybridization of incomplete and constraint programming techniques for solving Constraint Satisfaction Problems is generally restricted to some kind of master-slave combinations for specifc classes of problems. In this PhD thesis, we are concerned with the design of a hybrid resolution framework based on K.R. Apt's chaotic iterations. In this framework, basic resolution processes are abstracted by functions over an ordered structure. This allows us to consider the different resolution agents at a same level and to study more precisely various strategies for hybridization of local

search, genetic algorithms and constraint propagation. Hybrid resolution can be achieved as the computation of a fixed point of some specific reduction functions. Our framework opens up new and finer possibilities for hybridization/combination strategies. Our prototype implementation gave experimental results showing the interest of the model to design such hybridizations.

Keywords : CSP, local search, genetic algorithms, constraint propagation, hybrid resolution

-The "ozziKs" QCSP Solver

When a quantified CSP (QCSP) is claimed to be TRUE by some solver, how can we verify that such answer is correct?

In a standard CSP, it is just a matter of checking (in polynomial time) the values assigned to the variables by the solver  against each constraint in the CSP.

In the QCSP framework things are more complex: As a certificate we need a strategy. A strategy can be seen as a set of functions - one for each existentially quantified variable - yielding admissible values for existential variables as a function of some relevant subset of the universally quantified ones.

One such strategy is what we can actually check against the set of constraints to certify its validity.

Also, a strategy is a piece of information which is itself interesting (provided a "real-world" problem has been encoded into the underlying QCSP) as it provides an explicit scenario in which the validity of the quantified set of constraints is revealed.

For the case of quantified boolean constraints (QBFs), which we address here, strategies are also called simply certificates. 

The software "ozziKs", whose public availability we publicise here, is the implementation of an algorithm that: builds a certificate of satisfiability C(F) - a.k.a. strategy or policy or quantified model - for any given true Quantified Boolean Formula F for which a suited inference log is available (at present, only the QBF solver sKizzo produces a suited log); verifies C(F) against F, thus certifying in a solver-independent way the validity of F; evaluates user-provided expressions of various kinds over C(F); writes to file in different formats C(F) and/or the result of the evaluation of the above mentioned expressions.

A detailed user manual is available here. Linux, OS-X, and cygwin versions are available for download at http://sKizzo.info.
