Abstract

We present improved fast deterministic algorithm for integer sorting in linear space. Our algorithm sorts n integers in linear space in &Ogr;(n log log n log log log n) time. This improves the &Ogr;(n(log log n)3/2) time bound given in [6]. When the n integers in {0,1,…, m - 1} to be sorted satisfying log m ⪈(log n)2+∈, 0 &Ogr;(n log log n). These results are obtained by applying signature sorting on our previous result[6].
