Formalizing the XML Schema Matching Problem as a Constraint Optimization Problem
The first step in finding an efficient way to solve any difficult problem is making a complete, possibly formal, problem specification. This paper introduces a formal specifica...

Easy and hard coalition resource game formation problems: a parameterized complexity analysis
Coalition formation is a key topic in multi–agent systems (mas). Coalitions enable agents to achieve goals that they may not have been able to achieve independently, and encoura...

Using machine learning to make constraint solver implementation decisions
Programs to solve so-called constraint problems are complex pieces of software which require many design decisions to be made more or less arbitrarily by the implementer. These dec...

Impact of Constraints on the Complexity of Dynamic Spectrum Assignment
— In this paper we study the complexity of spectrum assignment problems in cognitive radio networks (CRNs) in the presence of several constraints. Although optimal spectrum assig...

Structural Analysis for Differential-Algebraic Systems: Complexity, Formulation and Facets
In this paper we consider the structural analysis problem for differential-algebraic systems with conditional equations. This consists, given a conditional differential algebraic ...
