Compact-table: efficiently filtering table constraints with reversible sparse bit-sets

J Demeulenaere, R Hartert, C Lecoutre… - Principles and Practice …, 2016 - Springer
In this paper, we describe Compact-Table (CT), a bitwise algorithm to enforce Generalized
Arc Consistency (GAC) on table constraints. Although this algorithm is the default propagator …

XCSP3: an integrated format for benchmarking combinatorial constrained problems

F Boussemart, C Lecoutre, G Audemard… - arXiv preprint arXiv …, 2016 - arxiv.org
We propose a major revision of the format XCSP 2.1, called XCSP3, to build integrated
representations of combinatorial constrained problems. This new format is able to deal with …

Xcsp3-core: A format for representing constraint satisfaction/optimization problems

F Boussemart, C Lecoutre, G Audemard… - arXiv preprint arXiv …, 2020 - arxiv.org
In this document, we introduce XCSP3-core, a subset of XCSP3 that allows us to represent
constraint satisfaction/optimization problems. The interest of XCSP3-core is multiple:(i) …

[HTML][HTML] STR3: A path-optimal filtering algorithm for table constraints

C Lecoutre, C Likitvivatanavong, RHC Yap - Artificial Intelligence, 2015 - Elsevier
Constraint propagation is a key to the success of Constraint Programming (CP). The
principle is that filtering algorithms associated with constraints are executed in sequence …

C Lecoutre, A Paparrizou, K Stergiou - Proceedings of the AAAI …, 2013 - ojs.aaai.org
One of the most widely studied classes of constraints in constraint programming (CP) is that
of table constraints. Numerousspecialized filtering algorithms, enforcing the wellknown …

Sliced table constraints: Combining compression and tabular reduction

N Gharbi, F Hemery, C Lecoutre, O Roussel - … of AI and OR Techniques in …, 2014 - Springer
Many industrial applications require the use of table constraints (eg, in configuration
problems), sometimes of significant size. During the recent years, researchers have focused …

Optimal and efficient filtering algorithms for table constraints

JB Mairy, P Van Hentenryck, Y Deville - Constraints, 2014 - Springer
Filtering algorithms for table constraints can be classified in two categories: constraint-based
and value-based. In the constraint-based approaches, the propagation queue only contains …

Decision diagrams: constraints and algorithms

G Perez - 2017 - theses.hal.science
Multivalued Decision Diagrams (MDDs) are efficient data structures widely used in several
fields like verification, optimization and dynamic programming. In this thesis, we first focus on …

[PDF][PDF] Automatic Synthesis of Smart Table Constraints by Abstraction of Table Constraints.

B Le Charlier, MT Khong, C Lecoutre, Y Deville - IJCAI, 2017 - academia.edu
The smart table constraint represents a powerful modeling tool that has been recently
