Questions: Consider the following Turing Machine:
A
a
b→ R
D
à, R
→ R
8.D
àȧ → R
a → R
b
B
→ R
Accept
b→ b, L
b→ L
a → L
b→ R
Note that the symbol à(b) is a marked a (b).
1. What is the sequence of configuration states starting at configurations given in the table on the reverse side of
this? Which of these strings are recognized? (You can fill out each column and then photo/scan it to include
with the rest of your solutions or recreate this electronically.)
2. What state is missing from the state diagram? Explain the convention for entering this state with an example
configuration in the state B whose next configuration enters this state. What about the state diagram let you
know that the next state was this missing state?
3. What do the self-loops on state B accomplish? What purpose this serve in the context of this Turing machine
deciding to accept or reject a string?
4. What do the self-loops on state Caccomplish? What purpose this serve in the context of this Turing machine
deciding to accept or reject a string?
5. What does the self-loop on state D accomplish? What purpose this serve in the context of this Turing machine
deciding to accept or reject a string?
