It seems to me that in a Trivial Decision Theory Problem, the list of stories is generated but then one of the stories hogs all the pros with everything else getting all the cons.
That wasn’t how I defined it. I defined it as a decision theory problem with literally one option.
The “screw this” option is available when we don’t insist that an agent is actually in a situation, just that a situation be simulated.
Speedup on evolution?
Maybe? Might work okayish, but doubt the best solution is that speculative.
