Insertion sortiterates, consuming one input element each repetition, and growing a sorted output list. Each iteration, insertion sort removes one element from the input data, finds the location it belongs within the sorted list, and inserts it there. It repeats until no input elements remain. ...

In this paper, we present a new mergesort algorithm which can sort n(= 2 h+1 1) elements using no more than n log 2(n+1) ( 13 12)n 1 element comparisons in the worst case. This algorithm includes the heap (fine heap) creation phase as a pre-processing step, and for each ...
