Abstract(in English) | A space-efficient linear-time approximation algorithm for the grammar-based compression problem, which requests for a given string to find a smallest context-free grammar deriving the string, is presented. The algorithm consumes only O(g_* log g_*) space and achieves the worst-case approximation ratio O(log g_* log n), with the size n of an input and the optimum grammar size g_*. Experimental results for typical benchmarks demonstrate that our algorithm is practical and efficient. |
