Exactly. Regardless of truth, it is an interesting model that could
well inform us about the truth. Provided it is tractable, of course,
which so far it has tended not to be (John Clark's criticism).
No, the UD does not need to be tractable, because the first person
are not aware of the delays.
John simply cannot understand this, because this needs step 3, 4, 5,
6, 7.
Sorry - you misunderstood me. In this case, I was referring to the
consequences of the AUDA, ie the programme of extracting physics
from COMP.
But that is tractable. The current algorithm that I provided makes it
untractable for complex propositions, but that is contingent (CP is NP-
complete too).
I would worry more if someone found a simple efficacious algorithm, as
this would raise a doubt that such logic incarnate quantum computing.
