Balanced Straight line programs(BSLPs) is one of the most powerful and general compression schemes. An BSLP is a context-free grammar which generates only one string. This paper studies an problem on compressed string described in terms of BSLP. In order to process compressed strings efficiently(in polynomial time with respect to the compressed size), decompression is never feasible.
We show efficient algorithm that testing square-freeness in $O(\max(n^2, n \log^2 N))$ time with $O(n^2)$ space, where $n$ and $N$ are the size of a given compressed string and the corresponding decompressed string, respectively. |
