Automatically Exploiting Symmetries in Constraint Programming
We introduce a framework for studying and solving a class of CSP formulations. The framework allows constraints to be expressed as linear and nonlinear equations, then compiles th...

New Developments in Symmetry Breaking in Search Using Computational Group Theory
Symmetry-breaking in constraint satisfaction problems (CSPs) is a well-established area of AI research which has recently developed strong interactions with symbolic computation, i...

Efficient Symmetry Breaking for Boolean Satisfiability
Identifying and breaking the symmetries of CNF formulae has been shown to lead to significant reductions in search times. In this paper we describe a more systematic and efficient...

Stokes-Dirac structures through reduction of infinite-dimensional Dirac structures
Abstract-- We consider the concept of Stokes-Dirac structures in boundary control theory proposed by van der Schaft and Maschke. We introduce Poisson reduction in this context and ...

Coordinate Structure Analysis with Global Structural Constraints and Alignment-Based Local Features
We propose a hybrid approach to coordinate structure analysis that combines a simple grammar to ensure consistent global structure of coordinations in a sentence, and features bas...
