A unified optimization framework for simultaneous gate sizing and placement under density constraints
—A unified optimization framework is presented for simultaneous gate sizing and placement. These processes are unified using Lagrangian multipliers, which synchronize the efforts...

Quadtrees for Embedded Surface Visualization: Constraints and Efficient Data Structures
The quadtree data structure is widely used in digital image processing and computer graphics for modeling spatial segmentation of images and surfaces. A quadtree is a tree in whic...

A New Approach for Heterogeneous Hybridization of Constraint Satisfaction Search Algorithms
In the recent years, CSP's have come to be seen as the core problem in many applications. We propose here a hybrid algorithm (MC-FC) that combines two different search method...

Constraint-Based Local Search for the Automatic Generation of Architectural Tests
Abstract. This paper considers the automatic generation of architectural tests (ATGP), a fundamental problem in processor validation. ATGPs are complex conditional constraint satis...

Lexicographically-ordered constraint satisfaction problems
Abstract. We describe a simple CSP formalism for handling multi-attribute preference problems with hard constraints, one that combines hard constraints and preferences so the two a...
