The recognition complexityof ordered set properties is considered, i.e.how many questions have to be asked to decide if an unknown ordered set has a prescribed property. We prove ...
While data compression and Kolmogorov complexity are both about effective coding of words, the two settings differ in the following respect. A compression algorithm or compressor...
The Positive-Negative Partial Set Cover problem is introduced and its complexity, especially the hardness-of-approximation, is studied. The problem generalizes the Set Cover probl...
In this paper we consider the problem of searching for the best match for an input among a set of vectors, according to some predetermined metric. Examples of this problem include...
We examine scattered hairpins, which are structures formed when a single strand of nucleotides folds into a partially hybridized stem and a loop. To specify different classes of h...
