A Constraint Programming Model for Scheduling the Unloading of Trains in Ports: Extended

no code implementations21 Dec 2023 Guillaume Perez, Gael Glorian, Wijnand Suijlen, Arnaud Lallouet

It is a problem that includes multiple parts such as splitting long trains into shorter ones and the routing of bulk material through a configurable network of conveyors to the stockpiles.

Efficient Projection Algorithms onto the Weighted l1 Ball

no code implementations7 Sep 2020 Guillaume Perez, Sebastian Ament, Carla Gomes, Michel Barlaud

In this paper we propose three new efficient algorithms for projecting any vector of finite length onto the weighted $\ell_1$ ball.

Compact-Table: Efficiently Filtering Table Constraints with Reversible Sparse Bit-Sets

no code implementations22 Apr 2016 Jordan Demeulenaere, Renaud Hartert, Christophe Lecoutre, Guillaume Perez, Laurent Perron, Jean-Charles Régin, Pierre Schaus

In this paper, we describe Compact-Table (CT), a bitwise algorithm to enforce Generalized Arc Consistency (GAC) on table con- straints.

Relations between MDDs and Tuples and Dynamic Modifications of MDDs based constraints

no code implementations11 May 2015 Guillaume Perez, Jean-Charles Régin

We study the relations between Multi-valued Decision Diagrams (MDD) and tuples (i. e. elements of the Cartesian Product of variables).
