The algorithm developed by Lempel and Ziv allows lossless compression, sans prior knowledge of the statistical properties of the data.

Mr. Zib on the left, Mr. Lempel on the right. Ziv and Lempel released the first version of the LZ algorithm, LZ77, in 1977. After that, in 1979, the second version, LZ79, was released.

Discover how this powerful algorithm measures randomness and compresses data—perfect for tech enthusiasts and curious minds alike!

He, alongside Professor Avraham Lempel, who died in February at the age of 86, developed the data compression algorithm Lempel-Ziv (LZ), which paved the way for the development of the ZIP, PDF ...
