Tournament sort Tournament sort Tournament sort is a sorting algorithm. It improves upon the naive selection sort by using a priority queue to find the next element in the sort. In the naive selection sort, it takes O("n") operations to select the next element of "n" elements; in a tournament sort, it takes O(log "n") operations (after building the initial tournament in O("n")). Tournament sort is a variation of heapsort. Tournament replacement selection sorts are used to gather the initial runs for external sorting algorithms. Conceptually, an external file is read and its elements are pushed into the priority queue until the
