    *Completely rewritten rebuttal of the halting theorem*

    A simulating halt decider (SHD) correctly predicts what the behavior of
    its input would be if it never aborted the simulation of this input. It
    does this by correctly recognizing several non-halting behavior patterns
    in a finite number of steps of correct simulation. It must abort the
    simulation of all non-terminating inputs so that it can report that they
    are non-halting. Inputs that do terminate are simply simulated until
    they complete.

    When simulating halt decider H correctly predicts that directly executed
    D(D) would remain stuck in recursive simulation (run forever) unless H
    aborts its simulation of D this directly applies to the halting theorem
    because H correctly determines:

    from a description of an arbitrary computer program and an input,
    whether the program will finish running, or continue to run forever.

    MIT Professor Michael Sipser has agreed that the following verbatim
    paragraph is correct (he has not agreed to anything else in this paper):

    (a) If simulating halt decider H correctly simulates its input D
    until H correctly determines that its simulated D would never stop
    running unless aborted then
    (b) H can abort its simulation of D and correctly report that D
    specifies a non-halting sequence of configurations.

    (b) is a necessary consequence of (a)

    01 int D(int (*x)())
    02 {
    03 int Halt_Status = H(x, x);
    04 if (Halt_Status)
    05 HERE: goto HERE;
    06 return Halt_Status;
    07 }
    08
    09 void main()
    10 {
    11 D(D);
    12 }

    *Here is the sequence when H never aborts it simulation*
    main() calls D(D) at line 11
    D(D) calls H(D,D) that simulates D(D) at line 03
    simulated D(D) calls simulated H(D,D) that simulates D(D) at line 03
    simulated D(D) calls simulated H(D,D) that simulates D(D) ...
    repeating ...

    Because it is an easily verified fact that D(D) would never stop running
    unless H aborts its simulation of D, H is necessarily correct to return
    0 indicating this verified fact.

    *This is every aspect of my whole proof*
    (a), (a) → (b) ∴ H(D,D)==0 is correct

    H(D,D) is fully operational in the x86utm operating system: https://github.com/plolcott/x86utm

    So, the criteria for a SHD is NOT the criteria for the Halting Problem,
    so unless you can actually PROVE them equivalent, you are just admitting
    that your Simulating Halt Deciders ar *NOT* HALT DECIDERS!!!


    When simulating halt decider H correctly predicts that directly executed
    D(D) would remain stuck in recursive simulation (run forever) unless H
    aborts its simulation of D this directly applies to the halting theorem because H correctly determines:

       from a description of an arbitrary computer program and an input,
       whether the program will finish running, or continue to run forever.
       https://en.wikipedia.org/wiki/Halting_problem

    So, how do you connect your simulation to the actual behavior of the
    machine in question?

    MIT Professor Michael Sipser has agreed that the following verbatim
    paragraph is correct (he has not agreed to anything else in this paper):

    (a) If simulating halt decider H correctly simulates its input D
    until H correctly determines that its simulated D would never stop
    running unless aborted then

    Which you H doesn't do according to the meaning of the words as
    Professor Sipser would use.

    His only definition of "Correctly determine that its simulated D would
    never stop running" would be that H determines that the UTM simulation,
    by an ACTUAL UTM, would never stop running.

    Since UTM D,D will halt because D(D) calls H(D,D) which you are saying
    will return 0, which will cause D(D) to Halt.

    Therefore, eiher you H returned 0 by breaking its requirement, or it
    juyst will never ever return and fail to be a decicer.

    You have admitted (by failing to provide rebutting proof) that Main
    calling H(D,D) and main calling D(D) calling H(D,D) will both return o

    (b) H can abort its simulation of D and correctly report that D
    specifies a non-halting sequence of configurations.

    (b) is a necessary consequence of (a)

    01 int D(int (*x)())
    02 {
    03   int Halt_Status = H(x, x);
    04   if (Halt_Status)
    05     HERE: goto HERE;
    06   return Halt_Status;
    07 }
    08
    09 void main()
    10 {
    11   D(D);
    12 }

    *Here is the sequence when H never aborts it simulation*
       main() calls D(D) at line 11
       D(D) calls H(D,D) that simulates D(D) at line 03
       simulated D(D) calls simulated H(D,D) that simulates D(D) at line 03
       simulated D(D) calls simulated H(D,D) that simulates D(D) ...
    repeating ...

    Which only happens if H never aborts, and simce you latter say H WILL
    abort, just shows you are doing unsound logic based on a false premise
    and thus becoming an admitted LIAR and HYPOCRITE.


    Because it is an easily verified fact that D(D) would never stop running unless H aborts its simulation of D, H is necessarily correct to return
    0 indicating this verified fact.

    But since H DOES abort its simulation, the above is just unsound logic,
    and your continued insistace proves you are of unsound mind.


    *This is every aspect of my whole proof*
    (a), (a) → (b) ∴ H(D,D)==0 is correct

    Nope.


    H(D,D) is fully operational in the x86utm operating system: https://github.com/plolcott/x86utm


    Right, and that program proves your logic to be unsound, as H does abort
    its simulation and returns 0 to D and thus D does halt.
