Erik D. Demaine, Dion Harmon, John Iacono, and Mihai Pǎtraşcu, “Dynamic Optimality–-Almost”, SIAM Journal on Computing, volume 37, number 1, May 2007, pages 240–251. Special issue of selected papers from the 45th Annual IEEE Symposium on Foundations of Computer Science.

We present an O(lg lg n)-competitive online binary search tree, improving upon the best previous (trivial) competitive ratio of O(lg n). This is the first major progress on Sleator and Tarjan's dynamic optimality conjecture of 1985 that O(1)-competitive binary search trees exist.
