A study of encodings of constraint satisfaction problems with 0/1 variables [PDF]

open access: yes, 2003
Many constraint satisfaction problems (csp's) are formulated with 0/1 variables. Sometimes this is a natural encoding, sometimes it is as a result of a reformulation of the problem, other times 0/1 variables make up only a part of the problem. Frequently

Prioritised fuzzy constraint satisfaction problems: axioms, instantiation and validation [PDF]

open access: yes, 2003
This paper identifies a generic axiom framework for prioritised fuzzy constraint satisfaction problems (PFCSPs), and proposes methods to instantiate it (i.e., to construct specific schemes which obey the generic axiom framework).

Phase transition behaviour in constraint satisfaction problems [PDF]

open access: yes, 1997
Many problems in artificial intelligence and computer science can be formulated as constraint satisfaction problems (CSPs). A CSP consists of a set of variables among which a set of constraints are imposed, with a solution corresponding to an assignment ...

The Constraint Satisfaction Problem: Complexity and Approximability

open access: yes, 2017
A backdoor set of a CSP instance is a set of variables whose instantiation moves the instance into a fixed class of tractable instances (an island of tractability).

Preventive maintenance scheduling with integer programming and constraint programming [PDF]

open access: yesمدیریت صنعتی, 2014
Preventive maintenance scheduling is to perform a series of tasks that prevents or minimizes production breakdowns and improves the reliability. Mathematical models have been developed to solve the preventive maintenance scheduling problem.

Sensitive instances of the Constraint Satisfaction Problem

open access: yesCoRR, 2020
We investigate the impact of modifying the constraining relations of a Constraint Satisfaction Problem (CSP) instance, with a fixed template, on the set of solutions of the instance. More precisely we investigate sensitive instances: an instance of the CSP is called sensitive, if removing any tuple from any constraining relation invalidates some ...

Distance Constraint Satisfaction Problems [PDF]

open access: yesInformation and Computation, 2010
We study the complexity of constraint satisfaction problems for templates $Γ$ that are first-order definable in $(\Bbb Z; succ)$, the integers with the successor relation. Assuming a widely believed conjecture from finite domain constraint satisfaction (we require the tractability conjecture by Bulatov, Jeavons and Krokhin in the special case of ...

Subsumption Algorithms for Three-Valued Geometric Resolution [PDF]

open access: yesLogical Methods in Computer Science, 2018
In our implementation of geometric resolution, the most costly operation is subsumption testing (or matching): One has to decide for a three-valued, geometric formula, if this formula is false in a given interpretation.

Generalized Majority-Minority Operations are Tractable [PDF]

open access: yesLogical Methods in Computer Science, 2006
Generalized majority-minority (GMM) operations are introduced as a common generalization of near unanimity operations and Mal'tsev operations on finite sets.
