    A sort sequence Sₙ is a sequence of all unordered pairs of indices in Iₙ={1,2,...,n}. With a sort sequence Sₙ, we associate a predictive sorting algorithm A(Sₙ) to sort input set X={x₁,x₂,..,xₙ} as follows. An execution of the algorithm performs pairwise comparisons of elements in the input set X as defined by the sort sequence, except that the comparisons whose outcomes can be inferred from the outcomes of the previous comparisons are not performed. The efficiency of a sorting algorithm is defined by the expected number of pairwise comparisons required. In this paper predictive sorting algorithms are obtained, based on known sorting algorithms, and are shown to be required on the average O(nlog n) comparisons.
