  • Sorting Algorithm 1 Sorting Algorithm
    Sorting algorithm 1 Sorting algorithm In computer science, a sorting algorithm is an algorithm that puts elements of a list in a certain order. The most-used orders are numerical order and lexicographical order. Efficient sorting is important for optimizing the use of other algorithms (such as search and merge algorithms) that require sorted lists to work correctly; it is also often useful for canonicalizing data and for producing human-readable output. More formally, the output must satisfy two conditions: 1. The output is in nondecreasing order (each element is no smaller than the previous element according to the desired total order); 2. The output is a permutation, or reordering, of the input. Since the dawn of computing, the sorting problem has attracted a great deal of research, perhaps due to the complexity of solving it efficiently despite its simple, familiar statement. For example, bubble sort was analyzed as early as 1956.[1] Although many consider it a solved problem, useful new sorting algorithms are still being invented (for example, library sort was first published in 2004). Sorting algorithms are prevalent in introductory computer science classes, where the abundance of algorithms for the problem provides a gentle introduction to a variety of core algorithm concepts, such as big O notation, divide and conquer algorithms, data structures, randomized algorithms, best, worst and average case analysis, time-space tradeoffs, and lower bounds. Classification Sorting algorithms used in computer science are often classified by: • Computational complexity (worst, average and best behaviour) of element comparisons in terms of the size of the list . For typical sorting algorithms good behavior is and bad behavior is .

Dean of the Graduate College II PREFACE The primary purpose of this project is to compare two new non-comparison sorting algorithms: Groupsort and Flashsort 1. To simplify discussion, we focus on the performance of these algorithms with integer data. First, we test Groupsort and Flashsort1 against bucket sort using uniformly distributed integer values with a number of different additional storage spaces and give run time performance curves. Then, we test Groupsort and Flashsortl against Quicksort using different distributed input data and give run time perfomance curves. Through the analysis of impact of run time, additional storage space, and data distribution, an optimal method is given to make each algonthm perform well. I sincerely thank my M.S. Committee - Drs.

  • Engineering Cache-Oblivious Sorting Algorithms
    Engineering Cache-Oblivious Sorting Algorithms Master’s Thesis by Kristoffer Vinther June 2003 Abstract Modern computers are far more sophisticated than simple sequential programs can lead one to believe; instructions are not executed sequentially and in constant time. In particular, the memory of a modern computer is structured in a hierarchy of increasingly slower, cheaper, and larger storage. Accessing words in the lower, faster levels of this hierarchy can be done virtually immediately, but accessing the upper levels may cause delays of millions of processor cycles. Consequently, recent developments in algorithm design have had a focus on developing algorithms that sought to minimize accesses to the higher levels of the hierarchy. Much experimental work has been done showing that using these algorithms can lead to higher performing algorithms. However, these algorithms are designed and implemented with a very specific level in mind, making it infeasible to adapt them to multiple levels or use them efficiently on different architectures. To alleviate this, the notion of cache-oblivious algorithms was developed. The goal of a cache-oblivious algorithm is to be optimal in the use of the memory hierarchy, but without using specific knowledge of its structure. This automatically makes the algorithm efficient on all levels of the hierarchy and on all implementations of such hierarchies. The experimental work done with these types of algorithms remain sparse, however. In this thesis, we present a thorough theoretical and experimental analysis of known optimal cache-oblivious sorting algorithms. We develop our own simpler variants and present the first optimal sub-linear working space cache-oblivious sorting algorithm.

  • In Search of the Fastest Sorting Algorithm
    In Search of the Fastest Sorting Algorithm Emmanuel Attard Cassar [email protected] Abstract: This paper explores in a chronological way the concepts, structures, and algorithms that programmers and computer scientists have tried out in their attempt to produce and improve the process of sorting. The measure of ‘fastness’ in this paper is mainly given in terms of the Big O notation. Keywords: sorting, algorithms orting is an extremely useful procedure in our information-laden society. Robert Sedgewick and Kevin Wayne have this to say: ‘In Sthe early days of computing, the common wisdom was that up to 30 per cent of all computing cycles was spent sorting. If that fraction is lower today, one likely reason is that sorting algorithms are relatively efficient, not that sorting has diminished in relative importance.’1 Many computer scientists consider sorting to be the most fundamental problem in the study of algorithms.2 In the literature, sorting is mentioned as far back as the seventh century BCE where the king of Assyria sorted clay tablets for the royal library according to their shape.3 1 R.

  • Making a Fast Unstable Sorting Algorithm Stable1
    Making a fast unstable sorting algorithm stable1 Arne Maus, [email protected] Department of Informatics University of Oslo Abstract This paper demonstrates how an unstable in place sorting algorithm, the ALR algorithm, can be made stable by temporary changing the sorting keys during the recursion. At ‘the bottom of the recursion’ all subsequences with equal valued element are then individually sorted with a stable sorting subalgorithm (insertion sort or radix). Later, on backtrack the original keys are restored. This results in a stable sorting of the whole input. Unstable ALR is much faster than Quicksort (which is also unstable). In this paper it is demonstrated that StableALR, which is some 10-30% slower than the original unstable ALR, is still in most cases 20-60% faster than Quicksort. It is also shown to be faster than Flashsort, a new unstable in place, bucket type sorting algorithm. This is demonstrated for five different distributions of integers in a array of length from 50 to 97 million elements. The StableALR sorting algorithm can be extended to sort floating point numbers and strings and make effective use of a multi core CPU.2 Keywords: stable sorting, radix, most significant radix, multi core CPU, Quicksort, Flashsort, ALR. 1. Introduction, sorting algorithms Sorting is maybe the single most important algorithm performed by computers, and certainly one of the most investigated topics in algorithm design. Numerous sorting algorithms have been devised, and the more commonly used are described and analyzed in any standard textbook in algorithms and data structures [Weiss, Aho] or in standard reference works [Knuth, van Leeuwen].

  • Buffered Adaptive Radix – a Fast, Stable Sorting Algorithm That Trades
    Buffered Adaptive Radix – a fast, stable sorting algorithm that trades speed for space at runtime when needed.1 Arne Maus, [email protected] Department of Informatics, University of Oslo Abstract This paper introduces Buffered Adaptive Radix (BARsort) that adds two improvements to the well known right-to-left Radix sorting algorithm (Right Radix or just Radix). The first improvement, the adaptive part, is that the size of the sorting digit is adjusted according to the maximum value of the elements in the array. This makes BARsort somewhat faster than ordinary 8-bit Radix sort (Radix8). The second and most important improvement is that data is transferred back and forth between the original array and a buffer that can be only a percentage of the size of the original array, as opposed to traditional Radix where that second array is the same length as the original array. Even though a buffer size of 100% of the original array is the fastest choice, any percentage larger than 6% gives a good to acceptable performance. This result is also explained analytically. This flexibility in memory requirement is important in programming languages such as Java where the heap size is fixed at load time and the new operator for constructing the extra array can terminate the program if the requested space is not available. BARsort avoids this problem. In this paper the stable BARsort algorithm is compared to the two non-stable algorithms Quicksort and Flashsort and the ordinary Radix8, which is stable. This is done for 14 different distributions of data and n, the length of the array, varying from 50 to 97M.
