Complexity of Extended vs. Classic , Parsers,classic method by Knuth [7] for . grammars, and the recent one by the authors [2], which directly builds the parser from . grammars represented as transition networks. For the . grammars, the classic Knuth’s method is indirect as it needs to convert them to .. We describe two parametric families of

State Complexity of Inversion Operations,e 2. (respectively, .). We consider the inversion operation where some substring of the given string is reversed. Formally, the inversion of a language . consists of all strings ... such that .?∈?.. We show that the nondeterministic state complexity of inversion is in Θ(..). We establish that the de

Cycles and Global Attractors of Reaction Systems,. In this work we continue a recent investigation of the complexity of detecting some interesting dynamical behaviours in reaction system. We prove that detecting global behaviours such as the presence of global attractors is . - complete. Deciding the presence of cycles in the dynamics and many oth

Computation Width and Deviation Number,ation tree of . on a given input. The deviation number of . on a given input counts the number of nondeterministic paths that branch out from the best accepting computation. Deviation number is a best-case nondeterminism measure closely related to the guessing measure of Goldstine, Kintala and Wotsc

Boundary Sets of Regular and Context-Free Languages,-boundary set of a language?. are those words that belong to?., where the .-predecessor or the .-successor of these words w.r.t. the prefix (suffix, respectively) relation is not in?.. For regular languages described by deterministic finite automata (DFAs) we give tight bounds on the number of state

Biclique Coverings, Rectifier Networks and the Cost of ,-Removal,.)?≥?.(.).. As a corollary, we establish that there exist nondeterministic finite automata (NFAs) with .-transitions, having . transitions total such that the smallest equivalent .-free NFA has Ω(..) transitions. We also formulate a version of previous bounds for the weighted set cover problem and d
