A Boundless Compression Algorithm in APL2

摘要

Compression algorithms are very useful for a variety of applications. Originally, their main use was what their name suggests, reducing the size of computer files without losing any information. It was interesting to see that they were equally useful for all types of files, such as text, bit maps, many types of images, sound, scientific experimental data, computer code (source and object code), combined data (text and images, for instance), and so on, and so forth. Only when the files have been coded with an imbedded compression algorithm (as happens in some image formats, such as JPEG, or in sound renditions in MP3) the additional compression by generalized algorithms is negligible.
