LZSS
From Just Solve the File Format Problem
LZSS is (1) a piece of computer software by Haruhiko Okumura, and (2) a vaguely-defined family of data compression algorithms and formats related to Okumura's LZSS, LZ77, and a certain subset of the methods discussed in Storer and Szymanski's 1982 paper Data Compression via Textual Substitution.
LZSS can perhaps be defined so broadly as to include all LZ77-like formats that remove the original LZ77's requirement that "match" and "character" codes must alternate. However, it is usually defined at least a little more narrowly, in particular to disallow matches that are deemed too short to be beneficial.
The name LZSS is almost certainly derived from Lempel–Ziv–Storer–Szymanski.
