Grailsort

Grailsort Youtube What is grailsort? tl;dr: grailsort is a complicated variant of mergesort that manages to cram all the extra space usually needed by mergesorts inside the array with a bit of magic involving square roots and unequal numbers!. Grailsort is a sorting algorithm in the block merge sort family, that runs in o ( n.

Grailsort is a sorting algorithm in the block merge sort family, that runs in o ( n log ⁡ n ) {\displaystyle o (n \log n)} , is stable, and not adaptive, and uses o ( 1 ) {\displaystyle o (1)} space. the algorithm starts by collecting a n × 2 {\displaystyle {\sqrt {n}}\times 2} of unique keys. The "real" timer in the video actually underestimates grailsort's speed, and i encourage you to check the stats in the links below. r.i.p. andrey astrelin. In 2013 astrelin (2013) published grailsort an implementation of huang and langston (1992) that was not dramatically slower than other mergesorts, hence deserved its name.

Grailsort for python comes with two modules: a strict one, and a slower one. the strict module (cgrailsort) only deals with array.array('d') objects, while the slower module (grailsort) deals with any python sequence that contains comparable objects. Grailsort for python comes with two modules: a strict one, and a slower one. the strict module (cgrailsort) only deals with array.array('d') objects, while the slower module (grailsort) deals with any python sequence that contains comparable objects. Grailsort stable in place sorting in o (n*log (n)) worst time. this algorithm is based on ideas from the article b c. huang and m. a. langston, fast stable merging and sorting in constant extra space (1989 1992) ( comjnl.oxfordjournals.org content 35 6 643.full.pdf). Grailsort is an in place, stable, worst case o (n log n) time variant of mergesort and implementation of 'block merge sort'. the algorithm starts by attempting to collect (2 * sqrt (n)) unique elements at the beginning of the array.
