Online Throughput-Competitive Algorithm for Multicast Routing and Admission Control
We present the first polylog-competitive online algorithm for the general multicast admission control and routing problem in the throughput model. The ratio of the number of reque...

Adaptive local ratio
Local ratio is a well-known paradigm for designing approximation algorithms for combinatorial optimization problems. At a very high level, a local-ratio algorithm first decomposes ...

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 ...

A Preemptive Algorithm for Maximizing Disjoint Paths on Trees
We consider the online version of the maximum vertex disjoint path problem when the underlying network is a tree. In this problem, a sequence of requests arrives in an online fash...

Topology Matters: Smoothed Competitiveness of Metrical Task Systems
We consider metrical task systems, a general framework to model online problems. Borodin, Linial and Saks [BLS92] presented a deterministic work function algorithm (WFA) for metric...
