Generalization (I am a kind of ...)
Specialization (... is a kind of me.)
Monte Carlo algorithm, Las Vegas algorithm, skip list insert, randomized binary search tree, reservoir sampling.
See also adversary, pseudo-random number generator, probabilistic algorithm, deterministic algorithm.
Note: Appearing in Dictionary of Computer Science, Engineering and Technology, Phillip A. Laplante ed., 2001, CRC Press LLC.
Some algorithms make random choices initially to avoid any fixed worst case.
