A Lagrangian Relaxation Approach for the Multiple Sequence Alignment Problem
Abstract. We present a branch-and-bound (bb) algorithm for the multiple sequence alignment problem (MSA), one of the most important problems in computational biology. The upper bou...

A revisit to floorplan optimization by Lagrangian relaxation
With the advent of deep sub-micron (DSM) era, floorplanning has become increasingly important in physical design process. In this paper we clarify a misunderstanding in using Lag...

Gate sizing for crosstalk reduction under timing constraints by Lagrangian relaxation
Abstract— This paper presents a post-route, timingconstrained gate-sizing algorithm for crosstalk reduction. Gate-sizing has emerged as a practical and feasible method to reduce ...

Floorplan area minimization using Lagrangian relaxation
modules can be handled in constraint graphs efficiently. This Floorplan area minimization is an important problem because many modules have shape flexibilities during the floorplan...

Real-World Extensions to a Production Scheduling Algorithm Based on Lagrangian Relaxation
In this article, we develop three eflcient extensions to a recent production scheduling algorithm based on Lagrangian relaxation [9]. These extensions handle the following real-wo...
