In the context of the LZW dictionary construction, denoted as LZW-flexible parsing (LZW-FP), it is demonstrated that optimality of FP translates into considerable improvement over greedy parsing in practice. A new data structure based on Karp-Rabin fingerprints is introduced to efficiently implement FP.
