Let INFINITE PDA = {<M>|M is a PDA and L(M) is an infinite language}. Show that INFINITE PDA is decidable.
5. Let CONTAINPDA DFA L(M1) C (M2)}. Show that CONTAIN PDA DFA is decidable. {{M1, M2) M1 is a PDA and M2 is a DFA such that = 5. Let CONTAINPDA DFA L(M1) C (M2)}. Show that CONTAIN PDA DFA is decidable. {{M1, M2) M1 is a PDA and M2 is a DFA such that =
Show that the following language is decidable. L={〈A〉 | A is a DFA that recognizes Σ∗ } M =“On input 〈A〉 where A is a DFA:
(c) Let Sigma = {0, 1}. Consider the problem of determining whether a PDA accepts some string that contains substring �101� is decidable. Formulate it as a language, and then show that this language is decidable
I need to prove follow: Let be a semi-decidable language. Then the language (Kleene star) is semi-decidable. We were unable to transcribe this imageWe were unable to transcribe this image
c) Determine the language, L, that is recognized by this PDA. q8 q7 c,b:A c) Determine the language, L, that is recognized by this PDA. q8 q7 c,b:A
9.) [30 points] Prove that, if a language L is decidable, then L can be enumerated in canonical order by some machine.
. Show that a language is decidable if and only if some enumerator prints the strings in the language in lexicographical order.
determine if the language is regular, context-free, Turing-decidable, or undecidable. For languages that are regular, give a DFA that accepts the language, a regular expression that generates the language, and a maximal list of strings that arc pairwise distinguishable with respect to the language. For languages that are context-free but not regular, prove that the language is not regular and either give a context- free grammar that generates the language or a pushdown automaton that accepts the language.
