Factor and suffix oracles have been introduced in [1] in order to provide an economic and efficient solution for storing all the factors and suffixes respectively of a given text. ...
We investigate the question whether NE can be separated from the reduction closures of tally sets, sparse sets and NP. We show that (1) NE RNP no(1)-T (TALLY); (2)NE RSN m (SPARS...
The Sort Transform (ST) can significantly speed up the block sorting phase of the Burrows-Wheeler transform (BWT) by sorting only limited order contexts. However, the best result o...
We introduce a new dimension to the widely studied on-line approximate string matching problem, by introducing an error threshold parameter so that the algorithm is allowed to mis...
