Other uses AT disambiguation lowercase In Unix like computer operating system s, the code at code command is used to schedule command computing command s to be executed once, at a particular system time time in the future. More precisely, it reads a series of commands from standard input and collects them into one at job which is carried out at a later date. The at job inherits the current environment, so that it is executed in the same working directory and with the same environment variable s set as when it was scheduled. It differs from code cron code which is used for recurring executions e.g. once an hour, every Tuesday, January 1 every year . As with code cron code , many Unix systems allow the administrator to restrict access to the code at code command. code at code can be made to mail a user when done carrying out a scheduled job of theirs, can use more than one job queue, and can read a list of jobs to carry out from a file instead of standard input.

In bubble sort, when any two elements are compared, they always have a gap distance from each other of 1. The basic idea of comb sort is that the gap can be much more than one.

At this point, comb sort continues using a gap of 1 until the list is fully sorted.

Orphan date February 2009 lowercase title sortsort is a function in C Standard Library that takes two random access iterators, the start and the end, as arguments and performs a comparison sort on the range of elements between the two iterators, front inclusive and end exclusive. The specific sorting algorithm is not mandated and may vary across implementations. The GNU Compiler Collection GNU Standard C library , for example, uses a hybrid sorting algorithm introsort is performed first, to a maximum depth given by 2× log sub 2 sub n , where n is the number of elements, followed by an insertion sort on the result. ref http gcc.gnu.org onlinedocs libstdc libstdc html USERS 4.4 a01027.html ...

A sorting algorithm falls into the adaptive sort family if it takes advantage of existing order in its input. It benefits from the presortedness in the input sequence or a limited amount of randomness disorder for various definitions of measures of disorder and sorts faster. Adaptive sorting is usually performed by modifying existing sorting algorithms. Motivation Comparison sort Comparison based sorting algorithms have traditionally dealt with achieving an optimal bound of Big O notation O n  logn when dealing with time complexity . Adaptive sort takes advantage of the existing order of the input to try to achieve better times, so that the time taken by the algorithm to sort is a smoothly growing function of the size of the sequence and the disorder in the sequence. In other words, the more presorted the input is, the faster it should be sorted. This is an attractive algorithm because nearly sorted sequences are common in practice. Thus, the performance of existing sort algorithms ... sorting algorithms that do optimally well in the worst case, notably heap sort and merge sort , do ... in the case of merge sort by checking if left.last item right.first item, in which case a merge operation ...

It improves upon the naive selection sort by using a priority queue to find the next element in the sort. In the naive selection sort, it takes math O n math operations to select the next element of math n math elements in a tournament sort, it takes math O log n math operations after building the initial tournament in math O n math . Tournament sort is a variation of heapsort . Common application Tournament replacement selection sorts are used to gather the initial runs for external sorting algorithms. Conceptually, an external file is read and its elements are pushed into the priority queue until the queue is full. Then the minimum element is pulled from the queue and written as part of the first run. The next input element is read and pushed into the queue, and the min is selected again and added to the run. There s a small trick that if the new element being pushed into the queue is less than the last element added to the run, then the element s sort value is increased so it will be part of the next run. On average, a run will be 100 longer than the capacity of the priority queue ref Donald Knuth, The Art of Computer Programming, Sorting and Searching, Volume 3, 1973. The snowplow argument.
