(9 pts 3 pts each) For each of the following languages, name the least powerful type of machine that will accept it, and prove your answer. (Hint: a finite state automata is less powerful than a pushdown automata, which in turn is less powerful than a Turing Machine.) For example, to prove a language needs a PDA to accept it, you would use the Pumping Lemma to show it is not regular, and then build the PDA or CFG that...

Give a PDA (Pushdown Automata) that recognizes the language L = {σ ∈ {x, y, z} ∗ | 2|σ|x = |σ|y ∨ 2|σ|y = |σ|z} You can choose whether your PDA accepts by empty stack or final state, but make sure you clearly note, which acceptance is assumed.

Can more than one stack be used, as in two stack push down
automata? YES!!! Please help!!!!
Bonus. Let QA denote a new class of abstract machines that act just like PDAs, except that the stack is replaced with a queue. Argue informally that QAs are at least as powerful as PDAs, in the sense that any language accepted by a PDA is also accepted by some QA. Hint: show that you can simulate a stack by using a queue.

Consider the language defined over the alphabet Σ (0, 1): [10] 2nin i. Show that L1 is context-free by specifying a CFG Gi for L1 ii. Convert the CFG Gi to a pushdown automaton Pv that accepts L1 by empty 12 stack iii. Give a pushdown automaton PF that accepts L by final state

Consider the pushdown automaton with the following transition rules: 1.8(0,0,20) = {(q,XZ0)} 2. 8(9,0,X) = {(q,XX)} 3. 8(q,1,X) = {(q,x)} 4. 8(q,£,X) = {(p,ɛ)} 5. 8(p,£,X) = {(p,ɛ)} 6.8(p,1,X) = {(p,XX)} 7. 8(p,1,20) = {(p,ɛ)} From the ID (p,1101,XXZ0), which of the following ID's can NOT be reached? (p,101,XZO) (p,101,XXXZO) (2,01,XXXXXZO) O (p,01,8) Here are the transitions of a deterministic pushdown automaton. The start state is qo, and f...

Stacks and Java 1. Using Java design and implement a stack on an array. Implement the following operations: push, pop, top, size, isEmpty. Make sure that your program checks whether the stack is full in the push operation, and whether the stack is empty in the pop operation. None of the built-in classes/methods/functions of Java can be used and must be user implemented. Practical application 1: Arithmetic operations. (a) Design an algorithm that takes a string, which represents an arithmetic...

please answer a,b, and c Consider the following Turing Machine. M = “On input hA,Bi where A and B are DFAs: 1. Iterate through strings in Σ∗ in shortlex order; where Σ represents the common symbols of their input alphabets. For each string iterated, simulate both A and B on it. 2. If a string is ever encountered that both A and B accept, then accept.” (a) (2 points) Give a description, in English, of the language that M recognizes....
