Consider the function defined by f(n) = 2 where n is a positive integer. (i) Can this function be computed by a Turing machine? Why or why not? (ii) Is this function primitive recursive? Why or why not?
Automata question Categorize the languages as I. Type 0 or Recursively Enumerable Languages II. Type 1 or CSL III. Type 2 or CFL IV. Type 3 or Regular in accordance to the Chomsky hierarchy (select only one of the answers designating the lowest level - Note that Type 3 is the lowest level and Type 0 is the highest level) over the alphabet {0,1} L = {0n10k |k, n is any integer} i think its type 0.. am i right ?...
Let us consider the following three statements: I. Recursively enumerable languages are those that can be accepted by a Turing machine; II. Recursive languages are those that can be decided by a Turing machine; III. A recursively enumerable language accepted by a Turing machine that halts is recursive. Which of the following holds? a.Only I; b.Only II; c.Only I and II; d.Only II and III; e. All I, II, and III.
Prove that the language is regular or not. {a^nb^m | n >= m and m <= 481}
1. If L is the complement of a language recognized by a non-deterministic finite automaton, then L is _______ a) finite b) regular but not necessarily finite c) deterministic context-free but not necessarily regular d) context-free but not necessarily deterministic context-free e) recursive (that is, decidable) but not necessarily context-free f) recursively enumerable (that is, partially decidable) but not necessarily recursive g) not recursively enumerable
Determining whether languages are finite, regular, context free, or recursive 1. (Each part is worth 2 points) Fill in the blanks with one of the following (some choices might not be used): a) finite b) regular but not finite d) context-free but not deterministic context-free e) recursive (that is, decidable) but not context-free f) recursively enumerable (that is, partially decidable) but not recursive g) not recursively enumerable Recall that if M is a Turing machine then "M" (also written as...
Let Σ = { a } , and consider the language L = { a n : n is a prime number } = { a 2 , a 3 , a 5 , a 7 , a 11 , . . . } . Is L a regular language? Why or why not? (Hint: L contains a 11 , a 17 , a 23 , a 29 , but not a 77 since 77 is divisible by 11. ....
Question 7. Let Σ = {a}, and consider the language L = {a^n : n is a prime number} = {a 2 , a3 , a5 , a7 , a11 , . . .}. Is L a regular language? Why or why not? (Hint: L contains a 11 , a 17 , a 23 , a 29, but not a 77 since 77 is divisible by 11. . . )
