Unlike the uniform treatment of symbols in different locations of an input file, a new approach is taken in the weighted dynamic compression method suggested in [1], which assigns higher priority to closer to be encoded symbols by means of an increasing weight function. The weighted method is especially suited for the encoding of files with locally skewed distributions. Empirical results have shown that weighted techniques can improve beyond the lower bound given by the entropy for static encoding.
