Stochastic approximation algorithm for optimal throughput performance of wireless LANs
In this paper, we consider the problem of throughput maximization in an infrastructure based WLAN. We demonstrate that most of the proposed protocols though perform optimally for ...

Optimal Scheduling of Contract Algorithms with Soft Deadlines
A contract algorithm is an algorithm which is given, as part of its input, a specified amount of allowable computation time. In contrast, interruptible algorithms may be interrupt...

An Optimal Algorithm for Querying Tree Structures and its Applications in Bioinformatics
Trees and graphs are widely used to model biological databases. Providing efficient algorithms to support tree-based or graph-based querying is therefore an important issue. In th...
