The suffix tree is a very powerful data structure developed originally for string matching and string searching. It has found many applications over the time and some of them belong into the data compression field. Many of these applications need a suffix tree built for a sliding window and there exist two clever algorithms by Fiala and Greene and by(More)
A close inspection of Fiala and Green's implementation of Ziv-Lempel'77 dictionary compression method reveals a surprising inefficiency. The match they are searching for from the root down the suffix tree can be obtained for free from the suffix tree construction algorithm! This observation suggests that the output of this compression method is in a way(More)
