Enumeration of Context-Free Languages and Related Structures
In this paper, we consider the enumeration of context-free languages. In particular, for any reasonable descriptional complexity measure for context-free grammars, we demonstrate ...

Some Results on Top-Context-Free Tree Languages
Top-context-free tree languages (called cor gulier by Arnold and Dauchet 1, 2]) constitute a natural subclass of context-free tree languages. In this paper, we give further evidenc...

Fast Nondeterministic Recognition of Context-Free Languages Using two Queues
We show how to accept a context-free language nondeterministically in O( n log n) time on a two-queue machine.

Nonterminal Complexity of Some Operations on Context-Free Languages
: We investigate context-free languages with respect to the measure Var of descriptional complexity, which gives the minimal number of nonterminals which is necessary to generate t...

GenInc: An Incremental Context-Free Grammar Learning Algorithm for Domain-Specific Language Development
- While grammar inference (or grammar induction) has found extensive application in the areas of robotics, computational biology, speech and pattern recognition, its application to...
