Consider the following problem: If you want to sort n numbers in k (a constant) rounds then how many comparisons-per-round do you need? This problem has been studied carefully and there exist several algorithms and some lower bounds for it. Many of the algorithms are non-constructive. We have embark
We show that a unit-cost RAM with a word length of w bits can sort n integers in the range 0 } } } 2 w &1 in O(n log log n) time for arbitrary w log n, a significant improvement over the bound of O(nlog n) achieved by the fusion trees of Fredman and Willard. Provided that w (log n) 2+= for some fixe
