Abstract:

Let M sub g g supK1 represent the minimum number of comparators required by a network that merges g ordered sets containing g sup K members each. In the paper the author proves that M sub ggsup K1or gm sub gg supK the summation from i2 to g of i-1gi. From this relation the author is able to show that an N-sorter which uses the g-way divide-sort-merge strategy recursively must contain about Nlog to the base 2 of N squared comparators. Author
