Another algorithm for this process finds the longest string in a table that is a prefix of the unscanned input; that is the (*) Lempel-Ziv Welch algorithm.
Richard Baraniuk developed the restricted amplification property in a "model-based sensing" algorithm named for this process, meant to optimize data collected for it. The Calgary and Silesia corpuses are used to test new algorithms of this type, one of which uses the move-to-front transform. One algorithm for this process constantly selects two characters of minimum frequency and merges them into one node. Another algorithm for this process finds the longest string in a table that is a prefix of the unscanned input; that is the (*) Lempel-Ziv Welch algorithm. A binary trie is used to create an optimal prefix-free code in the Huffman form of this process, which can be lossless or lossy. After this process has been done to files, they may have the extension dot tar or dot zip. For 10 points, name this process of decreasing the amount of data needed to store a file.
