That means the DIRECT EXECUTION of the program represented by the input does not halt, since that is the DEFINITION of the results of a correct simuation.

That also requires that the simulation does not stop until it reaches a final state. You H neither does that nor correctly determines that (since it does halt) thus you can never use the second paragraph to be allowed to abort, even though you do anyway, which is why you get the wrong answer.

Which isn't an ACTUALY correct emulation, but only a PARTIAL correct emulation (since correct emulation implies EVERY instruction but a terminal one is followed by the next instruction).

The key fact is that PARTIAL emulation doesn't reveal the future of the behavior past the point of the emulation.

 Nope, he just laid a trap that you fell into.
 

He could not have possibly laid any trap you dumb bunny.
All of the words were my own verbatim words. It took me
two years to compose those exact words.

The ONLY simulation that Professor Sipser accepts as correct, is one that shows EXACTLY the behavior of the machine being simulated.
 

So you are stupid enough to believe that professor Sipser
is stupid enough to to try and get away with disagreeing
with the semantics of the x86 language?
