Processes Taking Place In Pushdown Automation


Consider the following Pushdown Automaton (PDA) P1:
P1 = (Q = {q0, q1}, ∑ = {a, b, c}, ד = {0, 1, #}, δ, q0, Z0 = #, F = {q1}) where the transition function δ is given by:
δ (q0, a,#) = {(q0, 0#), (q0, 11#)}
δ (q0, a, 0) = {(q0, 00), (q0, 110)}
δ (q0, a, 1) = {(q0, 01), (q0, 111)}
δ (q0, b, 0) = {(q0, Î)}
δ (q0, c, 1) = {(q0, Î)}
δ (q0, Î,#) = {(q1,#)}

Acceptance is by final state.

Which of the following words are accepted by the PDA P1? Show the processes.

a.    ab
b.    aababcc
c.    ac


The question belongs to Computer Science and it discusses about the processes that take place in a Pushdown Automation P1.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
