Le tri à bulles ou tri par propagation est un algorithme de tri. Application du tri à bulles au tableau de nombres «5 1 4 2 8» ; pour chaque .. A Shell sort, different from bubble sort in that it moves elements to numerous swapping positions. Check out my latest presentation built on , where anyone can create & share professional presentations, websites and photo albums in minutes. Sort an array of elements using the Shell sort algorithm, a diminishing increment sort. The Shell sort (also known as Shellsort or Shell’s method) is named after its inventor, Donald Shell, who published the (de shellSort (A).

Sorting Algorithm This is a sorting algorithm. It may be applied to a set of data in order to sort it. Sort an array of elements using the Shell sort algorithm, a diminishing increment sort.

Shell sort is a sequence of interleaved insertion sorts based on an increment sequence. The increment size is reduced after each pass until the increment size is 1.

## Principaux algorithmes de tri

With an increment size of 1, the sort is a basic insertion sort, but by this time the data is guaranteed to be almost sorted, which is insertion sort’s “best case”. Empirical studies have shown a geometric increment sequence with a ratio of about 2.

This is a generic implementation of the shell sort.

Ada allows arrays to be indexed by integer or enumeration types starting at any value. This version deals with any kind or value of valid index type. Picture for array to be sorted is purely fictional, there’s no boundary check – hence: In addition to the “usual” array and array lenght parameters, you need to supply an area initialized to low-values to detail row-length and up to 10 sort keys defined as follows: This excerpt contains just enough of the procedure division to show the workings.

See the example for the bubble sort for a more complete program. Translated from pseudocode at Wikipedia. For a more complete explanation of the Eiffel sort tdi, see Bubble sort.
