We argue that the simplest possible balance
criterion---let the tree take any shape as long as its
height is logarithmic---can be used to produce very ef≠
ficient code. A general balanced tree is a plain binary
search tree with no balance information in the nodes.
Balance is maintained by partial rebuilding. This
data structure can be implemented very efficiently.
(In experiments, it performs better than the skip list
