Abstract
A compressing method for statistical data characteristics by finite exhaustive optimization is disclosed. First, the statistics of the repeat frequency of the same character with specific length in the data is gathered. Next, the finite exhaustive method is used to search an alternative length range, and serial numbers are used for the repeated language units in the alternative length range. The non repeated units are coded in accordance with a Huffman compression algorithm. When the data are dictionary data, the block uniqueness of the dictionary database is used to divide the huge data into small blocks and then compress the small blocks so as to increase the speed of data searching to further enhance the efficiency of data compression without increasing the complexity of decompression time.
