Contribution grade

Algorithms and data structures · ALGORITHM

Reference score120,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Presented the partition-based recursive sorting method now known as Quicksort and analyzed its storage and running-time behavior.

Scientific scope

The record is the exact 1962 Computer Journal article. Hoare’s shorter 1961 algorithm notices, later partition schemes, implementation refinements and AlphaDev sorting networks remain separate.
