PAQ

PAQ by Ed Avis is a popular text compression program that achieves high compression ratios on a variety of file types.

PAQ uses advanced statistical and modeling techniques to predict upcoming characters in a file, encoding the data more efficiently than traditional methods.

Yes, PAQ is released under an open-source license, allowing users to inspect and modify the code.

PAQ is predominantly written in C++.

Yes, PAQ can compress a wide range of file types, including text, images, and executables.

Yes, PAQ can take advantage of multi-core processors through multi-threading.

No, PAQ is typically used through command-line interfaces for compression and decompression.

Yes, PAQ's high compression ratios make it suitable for archiving files and saving storage space.

Yes, there are several versions of PAQ developed over the years with varying levels of complexity and performance.

No, PAQ's focus on high compression ratios may result in slower processing speeds compared to other compression algorithms not optimized for real-time tasks.
