Estimating arbitrary subset sums with few probes
Suppose we have a large table T of items i, each with a weight wi, e.g., people and their salary. In a general preprocessing step for estimating arbitrary subset sums, we assign e...

Bandwidth Guaranteed Routing for Ad Hoc Networks with Interference Consideration
The problem of computing bandwidth guaranteed paths for given flow requests in an ad-hoc network is complicated because neighboring links share the medium. We define the path wi...
