But I do know that I have seen long lists from Eliezer of problems that TDT does not solve that he thinks it ought to be improved so as to solve.
Since CDT and EDT don't solve those problems either, all this justifies saying is that TDT does better on some problems, and the same on others, not "worse on others".
For every possible decision theory, there is a "nemesis" environment - where it does extremely badly. That is no-free-lunch fall out.
