For efficiency in practice they make parameter choices which result in non-polynomial worst-case bounds (or at least, in versions for which a polynomial bound isn't known). Of course, you can always combine the two by running for a long time with the "efficient" parameter choices, and then if you haven't terminated yet, switching to the worst-case parameter choices.Anonymousnoreply@blogger.com
