Re: Strategy for Strange Card Game

(Stealing some of the terminology from a different thread.) If there is an optimal strategy, then nothing the opponent can do will score better on average than the optimal strategy. When both people are using the optimal strategy, no one will want to deviate from it because they will score worse on ...

No, this mimicking changes nothing. My program does not care if it hangs, it still returns that there is a paradox. And it does not care if it halts, it still returns that there is a paradox. And it does not care if it's calling itself to check itself and act accordingly, because there is, in fact,...

Let me try something here. Earlier you wanted to alter the archetypical halting problem solver pseudocode so it wouldn't be fooled by machines that try to do the opposite.

Re: Hunters and prey (Newcomb's paradox?)

After 3, you should have 4. Everyone swaps to a new strategy that has a higher success rate, and all the prey see how much better it works and don't use anything else. Unless the hunters -always- catch 80% of prey, not just because 80% are making the wrong choice - in that case it's meaningless as n...
