Although discovered some 30 years ago, the Heapsort algorithm is still not completely understood. Here we investigate the best case of Heapsort. Contrary to ลฝ . claims made by some authors that its time complexity is O n , i.e., linear in the ลฝ . number of items, we prove that it is actually O n log

We provide a sorting algorithm, Adaptive Heapsort, that optimally adapts to several known, and new, measures of presortedness. The algorithm is motivated by a new measure, called \(O s c\), which intuitively tells the oscillation within the input sequence. We show that Osc generalizes a number of me
