An improved approximation algorithm for the partial latin square extension problem
Previous work on the partial Latin square extension (PLSE) problem resulted in a 2-approximation algorithm based on the LP relaxation of a three-dimensional assignment IP formulat...

On Mismatches between Incremental Optimizers and Instance Perturbations in Physical Design Tools
The incremental, “construct by correction” design methodology has become widespread in constraint-dominated DSM design. We study the problem of ECO for physical design domains...

Incremental HMM Alignment for MT System Combination
Inspired by the incremental TER alignment, we re-designed the Indirect HMM (IHMM) alignment, which is one of the best hypothesis alignment methods for conventional MT system combi...
