Well... Actually. No. First of all, radix sort uses structural features to arrive at linear time, it doesn't incomplrtely sort the input.
Secondly, I've tried to get the white paper exposed here and it generally goes over like a lead balloon but:
http://www.diku.dk/hjemmesider/ansatte/henglein/papers/hengl...
Is the technique. It's an imposing 80 page paper even dedicated educators like Edward Kmett has trouble explaining trivially, but there is a talk here by the author to help sum it up: https://www.youtube.com/watch?v=sz9ZlZIRDAg
We've had some of Henglein's associates here to talk about it, too.
There is a Haskell implementation and it can really speed up certain types of operations. It's tricky to get the constants low in Haskell, but Kmett seems to have done a pretty good job.
