The heapsort algorithm can be divided into two phases: heap construction, and heap extraction. The heap is an implicit data structure which takes no space beyond the array of objects to be sorted; the array is interpreted as a complete binary tree where each array element is a node and each node's parent and child links are defined by simple arithmetic on the array indexes.
The patience sorting algorithm can be applied to process control. Within a series of measurements, the existence of a long increasing subsequence can be used as a trend marker. A 2002 article in SQL Server magazine includes a SQL implementation, in this context, of the patience sorting algorithm for the length of the longest increasing subsequence.
An example of stable sort on playing cards. When the cards are sorted by rank with a stable sort, the two 5s must remain in the same order in the sorted output that they were originally in. When they are sorted with a non-stable sort, the 5s may end up in the opposite order in the sorted output.
In computer science, smoothsort is a comparison-based sorting algorithm.A variant of heapsort, it was invented and published by Edsger Dijkstra in 1981. [1] Like heapsort, smoothsort is an in-place algorithm with an upper bound of O(n log n) operations (see big O notation), [2] but it is not a stable sort.
Stable sorting algorithms maintain the relative order of records with equal keys (i.e. values). That is, a sorting algorithm is stable if whenever there are two records R and S with the same key and with R appearing before S in the original list, R will appear before S in the sorted list.
The first Facebook game in PopCap Games's successful lineup of "Blitz" releases based on an original idea and intellectual property, the studio expected Solitaire Blitz to go out like gangbusters.
Kathleen Henkel started playing Solitaire with a pack of cards when she was ... For Henkel, a 68-year-old grandmother, it wasn't just love of the game, or even the glory of winning a world record ...
He worked with Donald E. Knuth to develop a two-heap data structure that they called a "priority deque", published as an exercise in The Art of Computer Programming in 1973. [ 18 ] [ 19 ] After moving to Canada in 1974, he worked for Bell-Northern Research Ltd., Ottawa (BNR) and Northern Telecom (Nortel) until retiring in 1995.
