It has been known since 1962 that the ambiguity problem for context-free grammars is undecidable. Ambiguity in context-free grammars is a recurring problem in language design and p...

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...

Angluin showed that the class of regular languages could be learned from a Minimally Adequate Teacher (mat) providing membership and equivalence queries. Clark and Eyraud (2007) sh...
