Finitely generated subgroups of free groups as formal languages and their cogrowth [PDF]
For finitely generated subgroups $H$ of a free group $F_m$ of finite rank $m$, we study the language $L_H$ of reduced words that represent $H$ which is a regular language.

Non-Deterministic Updates of Boolean Networks [PDF]
Boolean networks are discrete dynamical systems where each automaton has its own Boolean function for computing its state according to the configuration of the network.

Regular omega-Languages with an Informative Right Congruence [PDF]
A regular language is almost fully characterized by its right congruence relation. Indeed, a regular language can always be recognized by a DFA isomorphic to the automaton corresponding to its right congruence, henceforth the Rightcon automaton. The same

Token Games and History-Deterministic Quantitative-Automata [PDF]
A nondeterministic automaton is history-deterministic if its nondeterminism can be resolved by only considering the prefix of the word read so far. Due to their good compositional properties, history-deterministic automata are useful in solving games and

Higher-Order Pushdown Systems with Data [PDF]
We propose a new extension of higher-order pushdown automata, which allows to use an infinite alphabet. The new automata recognize languages of data words (instead of normal words), which beside each its letter from a finite alphabet have a data value ...

On h-Lexicalized Restarting Automata [PDF]
Following some previous studies on restarting automata, we introduce a refined model - the h-lexicalized restarting automaton (h-RLWW). We argue that this model is useful for expressing lexicalized syntax in computational linguistics.

Passive Learning of Deterministic Büchi Automata by Combinations of DFAs
We present an algorithm that constructs a deterministic Büchi automaton in polynomial time from given sets of positive and negative example words. This learner constructs multiple DFAs using a polynomial-time active learning algorithm on finite words as ...

Learning Cover Context-Free Grammars from Structural Data [PDF]
We consider the problem of learning an unknown context-free gram- mar from its structural descriptions with depth at most ℓ. The structural descriptions of the context-free grammar are its unlabelled derivation trees. The goal is to learn a cover context-

A Structural Construction of a Deterministic Position Automaton
Every regular expression can be transformed into a Nondeterministic Finite Automaton (NFA) with or without transitions. A well known algorithm called subset construction technique is used for conversion of NFA into DFA. In this paper, initially, the construction of the position automaton is given for the same.
