The memory usage of this algorithm can be greatly improved by the use of an in-place partition algorithm.
The memory usage of this algorithm can be greatly improved by the use of an in-place partition algorithm. It experiences linear parallelization speedup after pre-processing because it is a strong divide-and-conquer algorithm; the essential step of that pre-processing is choosing pivots. Invented by Hoar, it has drawbacks including numerical instability and a quadratic worst case corresponding to it changing nothing, but that worst-case can be ameliorated by using the competing mergesort at a certain level of refinement. For 10 points, name this sorting algorithm the common name of which refers to its celerity.
