New "just-in-time" models have been developed that use an expected constant number of bits (
While "Zip-zip" is a specific technical term, the broader ecosystem of "Zip" technology has seen critical updates recently: Updated Zipzip
Traditional are randomized binary search trees (BSTs) that "zip" nodes together based on assigned numeric ranks. While efficient, original zip trees suffered from a mathematical bias where smaller keys were often positioned closer to the root than larger keys, leading to uneven search times. New "just-in-time" models have been developed that use
), zip-zip trees ensure the expected depth of the smallest key is identical to the largest, resulting in a more uniform and balanced tree. leading to uneven search times. )
