Short question, is Newcomb's Problem still considered an open issue, or has the community settled on a definite decision theory that will yield the right answers yet?
From the 2013 survey results:
Well that's nice, but I had meant: have we come to a consensus on what sort of decision theory will auto-generate the right result, rather than merely writing down the result of the decision theory preinstalled in our brains and calling it correct? Has the "Paradox" part been formally resolved?
Because, you know, I don't want to post about it and then get told my thoughts were already thought five years ago and didn't actually help solve the problem.
Incarnations of UDT sufficient for this problem have been made completely formal.
Ummm.... link please?
Not for any mathematically rigorous value of “what sort”, as far as I can tell.
Great, I'm drafting a post.
A good decision theory performs well in many problems and not only in one problem. Having a decision theory that solves Newcomb's Problem but that doesn't perform well for other problems isn't helpful.
There isn't yet the ultimate decision theory that solves everything so I don't see how individual problems can be declared solved.
