ABSTRACT:
A dynamic numeric compression method that groups like elements of a data stream and stores the methodology steps to form the groupings so that the data stream can be recovered completely upon decompression. The grouping is accomplished moving an element until it is adjacent a like element wherein the adjacent like element is moved and the original element is returned to the front or its original place in the file. The process is continued until all like elements are positioned at the opposite end of the file resulting in a unique number of moves being required to group a known number of elements in a file of known size together. To decompress, the known size data file is recreated and then filled with elements by reversing the move process.
