The relative efficiency of data compression by LZW and LZSS

Research output: Contribution to journalArticlepeer-review


We explore the use of the LZW and LZSS data compression methods. These methods or some versions of them are very common in use of compressing different types of data. Even though on average LZSS gives better compression results, we determine the case in which the LZW perform best and when the compression efficiency gap between the LZW algorithm and its LZSS counterpart is the largest.
