A Heuristic for the Stacker Crane Problem on Trees Which Is Almost Surely Exact
Abstract Given an edge-weighted transportation network G and a list of transportation requests L, the Stacker Crane Problem is to find a minimum-cost tour for a server along the e...

Tabulation Based 5-Universal Hashing and Linear Probing
Previously [SODA'04] we devised the fastest known algorithm for 4-universal hashing. The hashing was based on small pre-computed 4-universal tables. This led to a five-fold i...

Dynamic data compression for wireless transmission over a fading channel
—We consider a wireless node that randomly receives data from different sensor units. The arriving data must be compressed, stored, and transmitted over a wireless link, where bo...
