Optimal Sliding-Window Strategies in Networks with Long Round-Trip Delays
— A method commonly used for packet flow control over connections with long round-trip delays is “sliding windows”. In general, for a given loss rate, a larger window size a...

Admission control to minimize rejections and online set cover with repetitions
We study the admission control problem in general networks. Communication requests arrive over time, and the online algorithm accepts or rejects each request while maintaining the...

Covering Trees and Lower-bounds on Quadratic Assignment
Many computer vision problems involving feature correspondence among images can be formulated as an assignment problem with a quadratic cost function. Such problems are computatio...

An improved approximation ratio for the minimum linear arrangement problem
We observe that combining the techniques of Arora, Rao, and Vazirani, with the rounding algorithm of Rao and Richa yields an O( √ log n log log n)-approximation for the minimum-...
