In this paper we investigate P systems whose compartments contain sets of symbolobjects rather than multisets of objects, as it is common in membrane computing. If the number of m...
Abstract. We present a new method for proving lower bounds in evolutionary computation based on fitness-level arguments and an additional condition on transition probabilities bet...
This article delves into the scoring function of the statistical paraphrase generation model. It presents an algorithm for exact computation and two applicative experiments. The f...
All classical -terms typable with disjunctive normal forms are shown to share a common computational behavior: they implement a local exception handling mechanism whose exact work...
We show that reachability and termination for lossy channel systems is exactly at level Fωω in the Fast-Growing Hierarchy of recursive functions, the first level that dominates...
