Just wanted to congratulate and thank Jens for a great choice for Kixgolf this round, and a well done checker, etc ... this Burrows-Wheeler algorithm was a great choice because from what I can see, theres about a half dozen different algorithms and approaches to use. Plus speaking for myself - it really held my interest over the entire contest period ... must have changed my approach three or four times in the course of play ... I think that most of the other players did as well ... great one to be sure !
