Abstract:
In this paper we study greedy in-place sorting algorithms which miraculously happen to work in reasonable time. Dumb-Sort which repeatedly compares all possible pairs of array cells sorts n elements in n − 1 cycles, or time O(n3). Not-So-Dumb-Sort, which only tests adjacent cells, also sorts in n − 1 cycles, or in time O(n2). Guess-Sort, a randomized version of Dumb-Sort, runs in expected time O(n2 log n). And Fun-Sort, an in-place variant of Insertion-Sort that performs repeated insertions by binary search into an initially unsorted array, sorts in time O(n2 log n).
