A Constrained Least Squares Approach to Interactive Mesh Deformation
In this paper, we propose a constrained least squares approach for stably computing Laplacian deformation with strict positional constraints. In the existing work on Laplacian def...

Complexity of Clausal Constraints Over Chains
We investigate the complexity of the satisfiability problem of constraints over finite totally ordered domains. In our context, a clausal constraint is a disjunction of inequaliti...

Tight Bounds on the Approximability of Almost-satisfiable Horn SAT and Exact Hitting Set}
We study the approximability of two natural Boolean constraint satisfaction problems: Horn satisfiability and exact hitting set. Under the Unique Games conjecture, we prove the fo...

Unsatisfiability Reasoning in ORM Conceptual Schemes
ORM (Object-Role Modeling) is a rich and well-known conceptual modeling method. As ORM has a formal semantics, reasoning tasks such as satisfiability checking of an ORM schema natu...
