Randomized competitive algorithms for successful and unsuccessful search

This paper studies the classical dictionary problem using a self-adjusting linear list. We designed and analyzed randomized, on-line algorithms for a sequence of successful and unsuccessful searches which are competitive with off-line algorithms. Our algorithms combined the ps bit technique which speeds up unsuccessful search with the randomized move-to-front scheme of Reingold et al., which they used to speed up successful search.link_to_subscribed_fulltex
