摘要：

We show that both the Lempel-Ziv-77 and the Lempel-Ziv-78 factorization of a text of length n on an integer alphabet of size sigma can be computed in O(n) time with either O(n lg sigma) bits of working space, or (1 + epsilon) n lg n + O(n) bits (for a constant epsilon > 0) of working space (including the space for the output, but not the text).
