Nondeterminism in specifications may be used for at least two different purposes. One is to express underspecification, which means that the specifier for the same environment beha...
We present a general logic of explicit knowledge represented as finite sets of logical formulae which can evolve by nondeterministic reasoning and communication. It is partly bas...
Abstract. We improve on some recent results on lower bounds for conversion problems for regular expressions. In particular we consider the conversion of planar deterministic finite...
Background: High complexity is considered a hallmark of living systems. Here we investigate the complexity of temporal gene expression patterns using the concept of Permutation En...
