Ordinary code analysis proves that H(D,D)==0 according to its criterion.
I have a friend with a masters degree in computer science that agreed to
this after a 75 minute phone discussion carefully analyzing the first
three pages of my paper. He also immediately agreed with the Sipser
approved criterion with no discussion needed.

But it does'nt meet the criteria, sincd it never correctly determines
that the correct simulation of its input is non-halting.

Are you dancing round the fact that PO tricked the professor?

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

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 H can abort its simulation of D and correctly report
that D specifies a non-halting sequence of configurations.
</Sipser Approved Verbatim Abstract>

*to this paper: Rebutting the Sipser Halting Problem Proof* https://www.researchgate.net/publication/364302709_Rebutting_the_Sipser_Halting_Problem_Proof

H(D,D) /does/ meet the criterion for PO's Other Halting problem
  -- the one no one cares about. D(D) halts (so H is not halt decider),
but D(D) would not halt unless H stops the simulation.
H /can/ correctly determine this silly criterion (in this one case)

This is the criterion that Ben erased from his reply:

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

so H is a POOH decider (again, for this one case -- PO is not
interested in the fact the POOH is also undecidable in general).

The correct simulation is the correct simulation who ever does
it, and since D will halt when run, the correct simulation of D
will halt.

Right, but that's not the criterion that PO is using, is it? I don't
get what the problem is. Ever since the "line 15 commented out"
debacle, PO has been pulling the same trick: "D(D) only halts
because..." was one way he used to put it before finding a more
tricky wording. For years, the project has simply been to find
words he can dupe people with.

*It is implausible that professor Sipser could be duped*
*into approving an abstract to a paper with this title*
*Rebutting the Sipser Halting Problem Proof*

I emailed Ben a copy of this and invited him to make a rebuttal.
Since he responded to my first email I know that it reached him.

I am sure that he knows there is no correct rebuttal and that is his
reason for not responding.
