When it is understood that HHH does simulate itself
simulating DDD then any first year CS student knows
that when each of the above are correctly simulated
by HHH that none of them ever stop running unless aborted.

WHich means that the code for HHH is part of the input, and thus there is just ONE HHH in existance at this time.

Since that code aborts its simulation to return the answer that you claim, you are just lying that it did a correct simulation (which in this context means complete)

All of them do abort and their simulation does not need an abort.

At least it is true for all aborting ones, such as the one you presented in Halt7.c.

My claim is that each of the above functions correctly
simulated by any termination analyzer HHH that can possibly
exist will never stop running unless aborted by HHH.
Can you affirm or correctly refute this?

 

Yes, I confirmed many times that we can confirm this vacuous claim, because no such HHH exists. All of them fail to do a correct simulation up to the point where they can see whether the input specifies a halting program.

 if DDD correctly simulated by any simulating termination
analyzer HHH never aborts its simulation of DDD then
(a) DDD simulated by HHH never stops running.
(b) Directly executed HHH() never stops running.
(c) Directly executed DDD() never stops running.
 

And thus that HHH isn't a correct Halt decider.
Since DDD changes ad becomes a different program if you change the HHH that it calls, those results can't be used with a different HHH that aborts.
That is just unsound logic, as most of your logic is.
That is how you build your lies.
