Show that the family of regular languages is closed under the given operations below The nor of two languages by nor(L, L2) = {w: w E L1...
Automata Question (3) Show that the family of deterministic context-free languages is not closed under union and intersection.
Automata, Languages and Computation Using the languages L1 = { (10)* 1(1+0) + (10)*} and L2 = { a(a*) }, construct an ei NFA that accepts the concatenation of the languages L1L2. Using the languages L1 = { (10)* 1(1+0) + (10)*} and L2 = { a(a*) }, construct an ei NFA that accepts the concatenation of the languages L1L2.
Explain the answer QUESTION 8 The classes of languages P and NP are closed under certain operations, and not closed under others, just like classes such as the regular languages or context-free languages have closure properties. Decide whether P and NP are closed under each of the following operations. 1. Union. 2. Intersection. 3. Intersection with a regular language. 4. Concatenation 5. Kleene closure (star). 6. Homomorphism. 7. Inverse homomorphism. Then, select from the list below the true statement. OP...
1. (10 points) Show that the Turing Decidable languages are closed under complementation. If L is Turing Decidable then so is the complement -L. 1. (10 points) Show that the Turing Decidable languages are closed under complementation. If L is Turing Decidable then so is the complement -L.
7. (1 point) The collection of recognizable languages is closed under: A. union. B. concatenation. C. star. D. intersection. E. All of the above. Page 3 of 8 8. (1 point) L is decided by a deterministic) TM containing 100 tapes in time t(n) where n denotes the length of an input string. Which one of the following represents the time complexity of an equivalent single tape (deterministic) TM which decides L? A. Oft(n) 100). B. Oſt(n)). C. O(t(n)99). D....
Prove that the class of regular languages is closed under intersection. That is, show that if ? and ? are regular languages, then ? ∩ ? = {? | ? ∈ ? ??? ? ∈ ?} is also regular. Hint:givenaDFA? =(?,Σ,?,?,?)thatrecognizes?andaDFA? =(?,Σ,?,?,?)that11111 22222 recognizes ?, construct a new DFA ? = (?, Σ, ?, ?0, ?) that recognizes ? ∩ ? and justify why your construction is correct.
Closure properties of P and NP. (a) Is P closed under union, intersection, concatenation, complement and star? Just answer ”yes” or ”no” for each operation. (b) Is NP closed under union, intersection, concatenation, complement and star? Just answer ”yes” or "no" for each operation.
