The first technique is to use the Burrows-Wheeler compression algorithm rather than Lempel-Ziv sequential algorithms.

第一种技术使用Burrows - Wheeler压缩算法而不是顺序Lempel - ziv算法。

The deflation algorithm used by gzip (also zip and zlib) is an open-source, patent-free variation of the LZ77 (Lempel-Ziv 1977) algorithm.

gzip(也称zip或zlib)所使用的算法是开源、无专利的LZ77 (Lempel - Ziv 1977)算法的变体。
