Optimal On-Line Algorithms to Minimize Makespan on Two Machines with Resource Augmentation
We study the problem of on-line scheduling on two uniformly related machines where the on-line algorithm has resources different from those of the off-line algorithm. We consider ...

Optimal and Online Preemptive Scheduling on Uniformly Related Machines
We consider the problem of preemptive scheduling on uniformly related machines. We present a semi-online algorithm which, if the optimal makespan is given in advance, produces an ...

Preemptive Online Scheduling: Optimal Algorithms for All Speeds
Our main result is an optimal online algorithm for preemptive scheduling on uniformly related machines with the objective to minimize makespan. The algorithm is deterministic, yet...

Preemptive scheduling on a small number of hierarchical machines
We consider preemptive offline and online scheduling on identical machines and uniformly related machines in the hierarchical model, with the goal of minimizing the makespan. In t...

Semi-Online Preemptive Scheduling: One Algorithm for All Variants
We present a unified optimal semi-online algorithm for preemptive scheduling on uniformly related machines with the objective to minimize the makespan. This algorithm works for a...
