A correct halt decider is a Turing machine T with one accept state and one reject state such that:
If T is executed with initial tape contents equal to an encoding of Turing machine X and its initial tape contents Y, and execution of a real machine X with initial tape contents Y eventually halts, the execution of T eventually ends up in the accept state and then stops.
If T is executed with initial tape contents equal to an encoding of Turing machine X and its initial tape contents Y, and execution of a real machine X with initial tape contents Y does not eventually halt, the execution of T eventually ends up in the reject state and then stops.
Your "definition" fails to specify "encoding". There is no standard
encoding of Turing machines and tape contents.
That is why I made the isomorphic x86utm system.
By failing to have such a concrete system all kinds
of false assumptions cannot be refuted.
If it were isnomorphic the same false assumtipns would apply to both.
They do yet I cannot provide every single details of
the source-code of the Turing machine because these
details would be too overwhelming.
So instead every author makes a false assumption that
is simply believed to be true with no sufficient basis
to show that it isn't true.
Once I prove my point as the x86 level I show how the
same thing applies to the Peter Linz proof.
Your recent presentations are so far from Linz' proof that they
look totally unrelated.
I must begin where people are so far no one even understands
the concept of recursive emulation.
I don't know about you but most of the participants of this discussion
seem to understand recursive simulation and how it differs from
recursion.
