735 | four optimizations discussed in Sedgewick: | |
736 | ||
737 | 1. Non-recursive, using an explicit stack of pointer that store the | |
738 | next array partition to sort. To save time, this maximum amount | |
739 | of space required to store an array of MAX_INT is allocated on the | |
740 | stack. Assuming a 32-bit integer, this needs only 32 * | |
741 | sizeof(stack_node) == 136 bits. Pretty cheap, actually. | |
742 | ||
743 | 2. Chose the pivot element using a median-of-three decision tree. | |
744 | This reduces the probability of selecting a bad pivot value and | |
745 | eliminates certain extraneous comparisons. | |
746 | ||
747 | 3. Only quicksorts TOTAL_ELEMS / MAX_THRESH partitions, leaving | |
748 | insertion sort to order the MAX_THRESH items within each partition. | |
749 | This is a big win, since insertion sort is faster for small, mostly | |
750 | sorted array segments. | |
751 | ||
752 | 4. The larger of the two sub-partitions is always pushed onto the | |
753 | stack first, with the algorithm then concentrating on the | |
754 | smaller partition. This *guarantees* no more than log (n) | |
755 | stack size is needed (actually O(1) in this case)! */ | |
