Abstract : Let M sub g (g sup(K+1)) 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 g(g(sup K+1))>or= g(m sub g)(g supK)+ the summation from i=2 to g of ((i1)g/i). From this relation the author is able to show that an Nsorter which uses the gway dividesortmerge strategy recursively must contain about N(log to the base 2 of N) squared comparators. (Author)
