A Cubic Time Extension of Context-Free Grammars

  title={A Cubic Time Extension of Context-Free Grammars},
  author={Pierre Boullier},
Context-free grammars and cubic parse time are so related in people’s minds that they often think that parsing any extension of context-free grammars must need some extra time. Of course, this is not necessarily true and this paper presents a generalization of context-free grammars which nonetheless still has a cubic parse time complexity. This extension, which defines a subclass of context-sensitive languages, has both a theoretical and a practical interest. The class of languages defined by… CONTINUE READING
