Linear Context-Free Rewriting Systems and Deterministic Tree-Walking Transducers
We show that the class of string languages generated by linear context-free rewriting systems is equal to the class of output languages of deterministic treewalking transducers. F...

An FPGA-Based Coprocessor for the Parsing of Context-Free Grammars
This paper presents an FPGA-based implementation of a co-processing unit able to parse context-free grammars of real-life sizes. The application elds of such a parser range from p...

Learning Context Free Grammars in the Limit Aided by the Sample Distribution
We present an algorithm for learning context free grammars from positive structural examples (unlabeled parse trees). The algorithm receives a parameter in the form of a finite se...

Active Context-Free Games
An Active Context-Free Game is a game with two players (Romeo and Juliet) on strings over a finite alphabet. In each move, Juliet selects a position of the current word and Romeo ...
