In the classical framework of computation theory (Turing machines),
simulation is not equivalent to execution, though they can approximate one
another.

To the best of my knowledge a simulated input

The simulation of the behaviour should be equivalent to the real

That is the same as saying a function with infinite
recursion must have the same behavior as a function
without infinite recursion.

Nope. Where does it say that?

And the simulation performed by each of these is the same up to the point that HHH aborts, as you have admitted on the record:

No moron they are not.
HHH performs one whole recursive emulation of DDD
than HHH1 ever does BEFORE HHH EVER ABORTS.

 Nope, if that was true you would have previously identified the divergence but failed to do so.
 

The code has proved that it is true for three years.
That you are too stupid to read the code is not a rebuttal.
