Abstract

The following results concerning context-free controlled ETOL systems are shown:
  • (CF)ETOL=(D2)ETOL=(DCF)ETOL

  • (RMOL)EDTOLLOG(CF)

  • EOL ⪵ (CF)EDTOL

  • OI ∩ IO ⪵ (CF)ETOL

Keywords

Control Word Membership Problem Tree Transducer Attribute Grammar Formal Language Theory 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
