Hi Jay, I did not do a timing comparison either, but any change in performance after switching to Kstem was not noticeable. Cheers... h

Hi Wagner, Thanks for the intro of KStem! I quickly scanned the original paper on KStem by Robert Krovetz but could not find any timing comparison data on KStem and Porter stem. I wonder how slow/fast Kstem is compared to Porter stem based on your use in your application? Jay Wagner,Harry wrote: > Mathieu, > It's not my Kstem. It was written by someone at Umass, Amherst.
