设T是一个长度相同的不同子串的集合,则它的基数称为T的第k个子串复杂度。最近,已被证明是高度重复字符串的良好可压缩性度量。在本文中,我们给出了在游程长度压缩形式的大小中的长度T,证明了它可以在时间和空间上计算,即在具有字长的Word-RAM模型中,在空间上对每个比特的整数进行排序的时间复杂度。
Letdenote the set of distinct substrings of lengthkin a stringT, then its cardinalityis called thek-th substring complexity ofT. Recently,has been shown to be a good compressibility measure of highly-repetitive strings. In this paper, givenTof lengthnin the run-length compressed form of size, we show thatcan be computed intime andspace, whereis the time complexity for sortingintegers withbits each inspace in the Word-RAM model with word size.
