Sorting Algorithms

WCRT, Runspace, Stability

AlgorithmCharacteristics
Selection Sort WCRT: Θ(n2) Runspace: in place Stable: no Generic: Forward iterators Comment: Improves to linear as input approaches sorted
Insertion Sort WCRT: Θ(n2) Runspace: in place Stable: yes Generic: Bidirectional
Heapsort WCRT: Θ(n log n) Runspace: in place Stable: no Generic: Random Access Comments: Widely spaced Swaps may cause paging
Quicksort WCRT: Θ(n2) Runspace: + Θ(n) Stable: no Generic: Smart Bidirectional Comments: AC = Θ(n log n)
Merge Sort (array) WCRT: Θ(n log n) Runspace: + Θ(n) Stable: yes Generic: Random Access Comments: Extra space costly in time
Merge Sort (list) WCRT: Θ(n log n) Runspace: in place Stable: yes Generic: Member Function Comments: in-place! But Lists are slow.
Counting Sort WCRT: Θ(n + k) Runspace: + Θ(k Stable: yes Comment: Function Object argument
Radix Sort WCRT: Θ(d(n + k)) Runspace: + Θ(k) Stable: yes
Bit Sort WCRT: Θ(nb) Runspace: + Θ(n) Stable: yes Comments: Use Bit function object in counting sort
Byte Sort WCRT: Θ(nB) Runspace: + Θ(n) Stable: yes Comments: Use Byte function object in counting sort
