Problem 1. Multi-Automata Decidability
For each of the following languages, state whether or not they are decidable. If a language is
decidable, give a proof (description of an algorithm) showing why. If not, give an argument as to
how this would contradict one of the undecidability results we saw in class.
(a)
L1 = {{D,G)| DFA D accepts a string or CFG G generates a string}
Solution:
(b)
L2 = {{D,T)| DFA D and decider T do not accept any of the same strings}
