The Best Radix Sorting

Radix sorting is widely used for its high efficiency.Generally,the radix used for radix sorting is 10.However,it is very significant to find a radix r_best that makes sorting time minimum.In this paper,we give a method to find r_best,analyse the complexity of the radix sorting which uses r_best as radix,present a way to improve the efficiency,and compare the speed of the radix sorting which uses r_best as radix with that of the radix sorting which uses 10 as radix.
