A model seeker: Extracting global constraint models from positive examples

N Beldiceanu, H Simonis - … Conference on Principles and Practice of …, 2012 - Springer
We describe a system which generates finite domain constraint models from positive
example solutions, for highly structured problems. The system is based on the global …

Global constraint catalog

N Beldiceanu, M Carlsson, JX Rampon - 2010 - diva-portal.org
This report presents a catalogue of global constraints where each constraint is explicitly
described in terms of graph properties and/or automata and/or first order logical formulae …

A linear time approximation scheme for Euclidean TSP

Y Bartal, LA Gottlieb - 2013 IEEE 54th Annual Symposium on …, 2013 - ieeexplore.ieee.org
The Traveling Salesman Problem (TSP) is among the most famous NP-hard optimization
problems. The special case of TSP in bounded-dimensional Euclidean spaces has been a …

Minizinc with functions

PJ Stuckey, G Tack - Integration of AI and OR Techniques in Constraint …, 2013 - Springer
Functional relations are ubiquitous in combinatorial problems–the Global Constraint Catalog
lists 120 functional constraints. This paper argues that the ability to express functional …

Using finite transducers for describing and synthesising structural time-series constraints

N Beldiceanu, M Carlsson, R Douence, H Simonis - Constraints, 2016 - Springer
We describe a large family of constraints for structural time series by means of function
composition. These constraints are on aggregations of features of patterns that occur in a …

N Beldiceanu, G Ifrim, A Lenoir, H Simonis - Principles and Practice of …, 2013 - Springer
We present an application to extract and solve constraint models from sample solutions of
the Unit Commitment Problem of EDF, which computes the power output for each power …

Global constraint catalog, (revision a)

MiniBrass: soft constraints for MiniZinc

A Schiendorfer, A Knapp, G Anders, W Reif - Constraints, 2018 - Springer
Over-constrained problems are ubiquitous in real-world decision and optimization problems.
Plenty of modeling formalisms for various problem domains involving soft constraints have …

Towards solver-independent propagators

JN Monette, P Flener, J Pearson - … on Principles and Practice of Constraint …, 2012 - Springer
We present an extension to indexicals to describe propagators for global constraints. The
resulting language is compiled into actual propagators for different solvers, and is solver …
