Polyadic Soft Constraints

2019
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, 2007
The 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), 2006
Preferences 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

2013
We 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, 2011
ABSTRACTThis 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.

Abstracting Soft Constraints

2000
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 ...
