We revisit the method of Kirschenhofer, Prodinger and Tichy to calculate the moments of number of comparisons used by the randomized quick sort algorithm. We reemphasize that this approach helps in calculating these quantities with less computation. We also point out that as observed by Knuth ...
Consider the randomized quick sort (i.e. the pivot is randomly chosen). Let the sorted arrayA=[b1,…,bn]A=[b1,…,bn]. PutAij={biis compared tobj}Aij={biis compared tobj}. Sincebibiis compared tobjbjiffbibiorbjbjis first pivot chosen from[bi,…,bj][bi,…,bj], thus each pair ...
If we unwind the recursion in Quicksort, the resulting iterative algorithm has a very simple structure: We add the points in the input one at a time. At each time, we maintain the partition of the real line formed by the currently added points. We also maintain, with each interval of ...

Alon and Spencer [3], to Habib, McDiarmid et al. [19], and to Motwani and Raghavan [24]. A randomized algorithm is an algorithm such that the behavior of the algorithm depends on an internal or external random source. I.e., on the same input but with different random sources, ...

The simplest and the most well known randomized geometric algorithm is Quicksort. Numerous randomized-incremental algorithms are not online though they add objects one at a time. This is because they maintain conflict information that depends on unadded objects. To convert these algorithms into truly...
