Improving Compression Using Words
Jan Platoš, Pavel Krömer · 2012
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.
