Finite-Tree Analysis for Constraint Logic-Based Languages
Abstract. Logic languages based on the theory of rational, possibly infinite, trees have much appeal in that rational trees allow for faster unification (due to the omission of t...

Interleaving Universal Principles and Relational Constraints over Typed Feature Logic
We introduce a typed feature logic system providing both universal implicational principles as well as definite clauses over feature terms. We show that such an architecture suppo...

Randomized Methods for Linear Constraints: Convergence Rates and Conditioning
We study randomized variants of two classical algorithms: coordinate descent for systems of linear equations and iterated projections for systems of linear inequalities. Expanding...

Constrained Decompositions of Integer Matrices and their Applications to Intensity Modulated Radiation Therapy
We consider combinatorial optimization problems arising in radiation therapy. Given a matrix I with non-negative integer entries, we seek for a decomposition of I as a weighted su...
