(in English) |
The decision problem "whether a context free grammar G generates all terminal strings or not" has been considered to be undecidable. We prove that this decision problem is decidable. Therefore, the 2nd halting problem of a Turing machine, the decision problem of a semi-Thue system and Post's correspondence problem are decidable. |
