Hypothesis-Driven Simulation Studiesaving unique factorization into elements of . is regular if . is regular, and from this deduce an quadratic upper and lower bound on the length of the shortest word not in uf(.). We observe that uf(.) need not be context-free if . is context-free..Next, we consider some variations on unique factoriz

The players have a joint objective to avoid an inadmissible decision, in spite of the uncertainty induced by the input..We show that the acceptor model based on consensus games characterises context-sensitive languages, and conversely, that winning stra

Kyle T. S. Pattinson,Richard G. Wiseth don’t cares, with the restriction that no two holes may be within distance two. We present and prove a necessary and sufficient condition for a word of even length (at least eight) to not derive any squares (such word is called non-squareable). The condition can be decided in .(.) time, where . i

By well-known algebraizations, these problems are closely linked with each other.
