(algorithm)
Definition: A heuristic that moves the target of a search to the head of a list so it is found faster next time.
Generalization (I am a kind of ...)
Self-organising_heuristic [Wikipedia].
See also move-to-root heuristic, transpose sequential search, self-organizing list.
Note: This technique speeds up linear search performance only if the target item is likely to be searched for again soon.
