  • Abstract
    The Lempel-Ziv data compression algorithm has the property that for finite-memory sources the redundancy ρn (defined as the difference between the average code rate and the entropy when the memory size is n) is O (log log n/log n). We suggest a new version of the algorithm with redundancy ρn=O (1/log n)
