I was thinking about how I’d implement HPMoR-style time-travel in a turing machine, actually.
It goes something like this:
Compute every possible future that doesn’t contradict something in the fixed past, including loops.
Whenever you find a paradox, delete that timeline.
Repeat.
That would generate a story we could read, no problem. It wouldn’t generate anyone who actually experiences paradoxes, either; to the degree those actually exist, they never get out of the subatomic level. It’s not clear to me whether or not this results in a universe that can usefully be experienced, though, or (more to the point) whether your future experiences match up with the type of experiences you remember.

..kind of odd.
