Talk:Deterministic context-free language
From Wikipedia, the free encyclopedia
I believe this is equivalent to the set of non-ambiguous context-free grammars? If it is then this would be useful to include on this page.
- Not that simple. All DCFLs have unambiguous CFGs, but is a proper subset. Per Hopcroft, Motwani & ullman, Intro automata theory, languages and computation, 2nd edition. Added to article. (See example of unambig CFG that is not DCFG now in article). RJFJR 00:08, 12 April 2007 (UTC)
Removed the word "obviously" because I honestly can't see why that CFG is not a DCFG. Rhebus 15:23, 6 June 2007 (UTC)
