Draw a Pushdown Automata for Strings of the form 0n1n1m0m
Using the alphabet {0,1,c}, construct a pushdown automata for the following Strings of the form wcwr where w is a any string of 0's and 1's and wr is w reversed.
What is the relation of context-free grammars and a Deterministic Pushdown Automata? Can a Deterministic Pushdown Automata recognize a regular language?
what is the minimal corresponding maching (Finite Automata,
Pushdown Automata, or Turing Machine) for each of the following
languages? State which method is being used
P3) What is the minimal corresponding machine (FA, PDA or TM) for each of the following languages? (You must provide proper explanations or proofs for your answer.) (30 points) o) L1 (every strings consist with a and b 0, 00,000), 0). (b) L2 balanced parenthesises , For example L2- (a) Ls ab" al n 20)...
Describe a pushdown automata (PDA) that accepts palindromes over the alphabet {a,b}. Is your PDA deter-ministic or nondeterministic.
Q1: Assume S = {a, b}. Build a Pushdown Automata for odd number of a’s and odd number of b’s including ˄. Q2: Assume S = {a, b}. Build a Turing Machine for odd number of a’s and odd number of b’s.
Give deterministic pushdown automata to accept the following languages. a) {0n1m | n<=m}. b) {0n1m | n>=m}. c) {0n1m0n | n and m are arbitraty}.
this problem is about pushdown
automata:
4. (10 points) Explain in English what each of the following transition labels mean: a. 2,272 b. a, i = 2 C. a, A+B d. a, a →B e. a, A1
6. Consider a Pushdown Automata with TWO STACKS. Show that this machine is more powerful than a single stack PDA. (Use the language L = {a"\"c"which is not a CFL. Explain bow a two stack automata can accept this language.) HINT : Give a table representation of the 2PDA - it should have 7 columns : state, input, stack 1, stack 2, new state, stack 1 operation, stack 2 operation.
2. [10 marks] Give a PDA (Pushdown Automata) that recognizes the language L = {o€ {n,y, z}* | 2|이|z = |0ly V 2\이 You can choose whether your PDA accepts by empty stack or final state, but make sure you clearly note, which acceptance is assumed

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.
