We propose a formalism for manipulating soft constraints based on polyadic algebras. The choice of such algebras in place of classical cylindric ones simplifies the structure of the partial order of preference values by removing diagonals, a family of constants used for modelling parameter passing and variable substitution, whose presence require ...

Soft constraint based pattern mining
Data & Knowledge Engineering, 2007The paradigm of pattern discovery based on constraints was introduced with the aim of providing to the user a tool to drive the discovery process towards potentially interesting patterns, with the positive side effect of achieving a more efficient computation. So far the research on this paradigm has mainly focused on the latter aspect: the development

Uncertainty in soft constraint problem
International Conference on Computational Intelligence for Modelling, Control and Automation and International Conference on Intelligent Agents, Web Technologies and Internet Commerce (CIMCA-IAWTIC'06), 2006Preferences and uncertainty occur in many real-life problems. The theory of possibility is one way of dealing with uncertainty, which allows for easy integration with fuzzy preferences. In this paper we consider an existing technique to perform such an integration and, while following the same basic idea, we propose to generalize it to other classes of

Constraint Relationships for Soft Constraints
2013We introduce constraint relationships as a means to define qualitative preferences on the constraints of soft constraint problems. The approach is aimed at constraint satisfaction problems (CSPs) with a high number of constraints that make exact preference quantizations hard to maintain manually or hard to anticipate—especially if constraints or ...

Soft Budget Constraint Reconsidered
Bulletin of Economic Research, 2011ABSTRACTThis paper demonstrates that Kornai's original concept of the soft budget constraint (SBC) as a theoretical innovation in micro‐theory disguises income redistributions that are essentially macroeconomic relationships. The SBC also postulates a competitive market economy as the benchmark of hard budget constraint (HBC) and efficiency.

We propose an abstraction scheme for soft constraint problems and we study its main properties. Processing the abstracted version of a soft constraint problem can help us in many ways: for example, to find good approximations of the optimal solutions, or also to provide us with information that can make the subsequent search for the best solution ...

Tradeoff Generation Using Soft Constraints
2004Tradeoffs have been proposed in the literature as an approach to resolving over-constrainedness in interactive constraint-based tools, such as product configurators. It has been reported how tradeoffs can be modeled as additional constraints. This paper presents a formal framework for tradeoff generation based on the semiring approach to soft ...

Soft Constraints for Lexicographic Orders
2013While classical Constraint Satisfaction Problems (CSPs) concern the search for the boolean assignment of a set of variables that has to satisfy some given requirements, their soft variant considers ordered domains for assignments, thus modeling preferences: the aim is to provide an environment where suitable algorithms (e.g.

Federalism and the Soft Budget Constraint [PDF]
SSRN Electronic Journal, 1999 The government's incentives to bail out inefficient projects are determined by the trade-off between political benefits and economic costs, the latter depending on the decentralization of government. Two effects of federalism are derived: First, fiscal competition among local governments under factor mobility increases the opportunity costs of bailout ...

Scheduling with soft constraints
Proceedings of the 2009 International Conference on Computer-Aided Design, 2009In a behavioral synthesis system, a typical approach used to guide the scheduler is to impose hard constraints on the relative timing between operations considering performance, area, power, etc., so that the resulting RTL design is favorable in these aspects.
