Proving Conjectures Acquired by Composing Multiple Biases

no code implementations14 Dec 2023 Jovial Cheukam-Ngouonou, Ramiz Gindullin, Nicolas Beldiceanu, Rémi Douence, Claude-Guy Quimper

We present the proofs of the conjectures mentioned in the paper published in the proceedings of the 2024 AAAI conference [1], and discovered by the decomposition methods presented in the same paper.

Classifying Pattern and Feature Properties to Get a $Θ(n)$ Checker and Reformulation for Sliding Time-Series Constraints

no code implementations3 Dec 2019 Nicolas Beldiceanu, Mats Carlsson, Claude-Guy Quimper, Maria-Isabel Restrepo-Ruiz

Given, a sequence $\mathcal{X}$ of $n$ variables, a time-series constraint ctr using the Sum aggregator, and a sliding time-series constraint enforcing the constraint ctr on each sliding window of $\mathcal{X}$ of $m$ consecutive variables, we describe a $\Theta(n)$ time complexity checker, as well as a $\Theta(n)$ space complexity reformulation for such sliding constraint.

Synthesising a Database of Parameterised Linear and Non-Linear Invariants for Time-Series Constraints

no code implementations15 Jan 2019 Ekaterina Arafailova, Nicolas Beldiceanu, Helmut Simonis

Many constraints restricting the result of some computations over an integer sequence can be compactly represented by register automata.

Global Constraint Catalog, Volume II, Time-Series Constraints

no code implementations26 Sep 2016 Ekaterina Arafailova, Nicolas Beldiceanu, Rémi Douence, Mats Carlsson, Pierre Flener, María Andreína Francisco Rodríguez, Justin Pearson, Helmut Simonis

First this report presents a restricted set of finite transducers used to synthesise structural time-series constraints described by means of a multi-layered function composition scheme.

Propagating Regular Counting Constraints

no code implementations27 Sep 2013 Nicolas Beldiceanu, Pierre Flener, Justin Pearson, Pascal Van Hentenryck

Constraints over finite sequences of variables are ubiquitous in sequencing and timetabling.
