We present an improvement of Rytter's algorithm that constructs a straight-line program for a given text and show that the improved algorithm is optimal in the worst case with respect to the number of AVL-tree rotations. Also we compare Rytter's and ours algorithms on various data sets and provide a comparative analysis of compression ratio achieved by these algorithms, by LZ77 and by LZW.
