Abstract

General compression algorithms were designed for usage characters as basic symbols. Later, algorithm which used words were developed. The problem is that there is no clear line which defines if is better to use characters or words. In this paper, we developed optimization algorithm based on simulated annealing that selects only several words from all possible words and combine them with character to improve overall compression. The achieved results are very promising.

使用单词改进压缩
针对常用字符作为基本符号,设计了通用的压缩算法。后来,使用文字的算法被开发出来。问题是,没有明确的界限来定义使用字符或单词是否更好。在本文中,我们开发了一种基于模拟退火的优化算法,从所有可能的单词中只选择几个单词并将它们与字符组合以提高整体压缩。取得的成果是很有希望的。
