Skip lists are a practical, probabilistic data structure that can be used in place of balanced trees. Algorithms for insertion and deletion in skip lists are much simpler and significantly faster than equivalent algorithms for balanced trees. This paper describes and analyzes skip lists and presents new techniques for analyzing probabilistic algorithms.
