I am working on providing an academic quality definition of this
term.
The definition in Wikipedia is good enough.
I think he means, he is working on a definition that redefines the field to allow him to claim what he wants.
Here one can claim whatever one wants anysay.
In if one wants to present ones claims on some significant forum then
it is better to stick to usual definitions as much as possible.
Sort of like his new definition of H as an "unconventional" machine that some how both returns an answer but also keeps on running.
There are systems where that is possible but unsolvable problems are
unsolvable even in those systems.
When Ĥ is applied to ⟨Ĥ⟩
Ĥ.q0 ⟨Ĥ⟩ ⊢* embedded_H ⟨Ĥ⟩ ⟨Ĥ⟩ ⊢* Ĥ.qy ∞
Ĥ.q0 ⟨Ĥ⟩ ⊢* embedded_H ⟨Ĥ⟩ ⟨Ĥ⟩ ⊢* Ĥ.qn
This notation does not work with machines that can, or have parts
that can, return a value without (or before) termination.
⊢* specifies a wildcard set of state transitions that could
include a transition to a non-final state embedded_H.qn.
The term "wildcard" is usually not used in this context. And the word
"set" is not sufficiently specific, so "sequence" should be used instead.
Yes that is better.
⊢* specifies a wildcard sequence of state transitions
That still has the problem that "wildcard" has no well known meaning
that could be applicable in that context.
*Here is how Linz says it*
The Linz term “move” means a state transition and its corresponding
tape head action {move_left, move_right, read, write}.
⊢* indicates an arbitrary number of moves.
I.e., a sequence of moves.
Anyway, the language cannot handle a situation where one part of a
machine gives its result to another parts and then both continue their
execution.
The language of Turing machine descriptions certainly can handle
TM's that do not halt. It can also handle transitioning through
a specific state to another state.
Yes, but a machine were one part of a machine gives its result to
aonter part and then both continue their exection is not a Truing
machine. Consequently, when you introduced that possibility were
not discussing Turing machines. A language decined for Turing
mahihes is not sufficient for non-Turing machines.
This specific state can encode a halt status value. New ideas are
hard because there is no standard boiler-plate that can be applied
to them.
The specification of the halt decider requires that the halt status
value is indicated by the final state.
