内容：
The search tree is a classical and ubiquitous data structure, fundamental to databases and many other computer applications. The AVL tree, a type of balanced binary tree, was invented fifty years ago; since then, many different kinds of search trees have been described, analyzed, and used. Yet the design space is vast, and mysteries remain. This talk will describe recent work by the speaker and his colleagues that has produced a new framework for defining and analyzing balanced search trees, a new kind of balanced tree with especially nice properties, and a way to maintain balance by rebalancing only on insertion, not on deletion.
