Turing machines are not self-modifying code, so you cannot tell it to "add a state."

If this restriction is in their specification, then it would seem to form a lack of correspondence to actual hardware machines, thus making them less than an ideal model of computation.

I assume you are OK with the TM definition at

http://en.wikipedia.org/wiki/Turing_machine#Formal_definition

That treats the state table as a separate structure, not part of the tape.

It includes a sample state table. Can you show, in the same format, the

rows that would change the state table?
