A New Axiomatic Framework for Prioritized Fuzzy Constraint Satisfaction Problems
2000The paper introduces an axiomatic framework for prioritized fuzzy constraint satisfaction problems (PFCSPs), in which the notion of global satisfaction degree is based on three intuitive axioms. First, if a constraint with the highest priority in a PFCSP is completely violated by a variable assignment, the variable assignment cannot be a solution to ...

Spread-Repair-Shrink: A Hybrid Algorithm for Solving Fuzzy Constraint Satisfaction Problems
2006 IEEE International Conference on Fuzzy Systems, 2006A fuzzy constraint satisfaction problem (FCSP) is an extension of the classical CSP, a powerful tool for modeling various problems based on constraints among variables. Basically, the algorithms for solving CSPs are classified into two categories: the systematic search (complete methods based on search trees) and the local search (approximate methods ...

Fuzzy control over constraint satisfaction problem solving in structural design
[Proceedings 1993] Second IEEE International Conference on Fuzzy Systems, 2002The authors address the problems of usual constraint satisfaction (CSP) in structural design and present a technique to control the design by applying a new model called the fuzzy constraint satisfaction problem (FCSP). In FCSP both the constraints and the domains of variables are allowed to be fuzzy.

On solving fuzzy constraint satisfaction problems with genetic algorithms
1998 IEEE International Conference on Evolutionary Computation Proceedings. IEEE World Congress on Computational Intelligence (Cat. No.98TH8360), 2002An attempt to solve fuzzy constraint satisfaction problems (FCSPs) with the use of genetic algorithms (GAs) is presented in the paper. A fuzzy relation that represents the degrees of satisfaction of fuzzy constraints in a given FCSP is considered as an objective function of the respective unconstrained optimization problem.

On Linguistic Fuzzy Constraint Satisfaction Problems
1999Fuzzy constraint satisfaction problems (FCSPs) extend standard (crisp) constraint satisfaction problems (CSPs) by introducing a notion of fuzzy constraints. Fuzzy constraints allow one to express the degrees to which the constraints are satisfied with a given instantiation of constrained variables. The main advantage of FCSPs is flexibility in handling

Flexible Widget Layout Formulated as Fuzzy Constraint Satisfaction Problem
2009We show an improvement of our previous work, a formulation of the flexible widget layout (FWL) problem as a fuzzy constraint satisfaction problem (FCSP) and a method for solving it. The automation of widget layout is one of the most important challenges for the generation of graphical user interfaces (GUIs).

Field-Based Fuzzy Spatial Reasoning Model for Constraint Satisfaction Problem
2011Humans' representation about geographic phenomena in natural language is usually qualitative rather than quantitative. Qualitative spatial reasoning provides an approach which is considered to be closer to the representation. Commercial GIS software is being confronted with a challenge that the software should be equipped with artificial intelligent ...

Knowledge sharing among partners from a distributed engineering team is becoming more critical for decision making. The work presented in this article proposes to support users of an agent based application for collaborative product design, during the definition of an engineering problem under a Constraint Satisfaction Problem (CSP) approach. The scope

Crop management planning as a fuzzy and uncertain constraint satisfaction problem
1995A crop management plan is a logical and ordered sequence of cultivation operations applied to a crop. Several possible approaches to the crop management planning problem have been considered. One sees the planning task as a constraint satisfaction problem (CSP).
