Polylog space compression is incomparable with Lempel-Ziv and pushdown compression
Mayordomo, Elvira and Moser, Philippe (2009) Polylog space compression is incomparable with Lempel-Ziv and pushdown compression. In: SOFSEM '09 Proceedings of the 35th Conference on Current Trends in Theory and Practice of Computer Science. Springer verlag, Berlin, pp. 633-644. ISBN 9783540958901 AbstractThis paper considers online compression algorithms that use
at most polylogarithmic space (plogon). These algorithms correspond
to compressors in the data stream model. We study the performance
attained by these algorithms and show they are incomparable with both
pushdown compressors and the Lempel-Ziv compression algorithm. | Additional Information: | © ACM, 2009. This is the author's version of the work.
