The 5-and-10 problem addresses the question of how to construct a theory of logical counterfactuals.
Another version, sometimes known as the heavy ghost problem, is a problem in certain types of UDT-like decision theories, when the fact that a counterfactual is known to be false makes the algorithm implement it.
Let there be a decision problem which involves the choice between $5 and $10, a utility function that values the $10 more than the $5, and algorithm A optimizing for this utility function.
Another version, sometimes known as the heavy ghost problem, israises a problem indifficulty with certain types of UDT-like decision theories, when the fact that a counterfactual is known to be false makes the algorithm implement it.
Specifically, let there be a decision problem which involves the choice between $5 and $10, a utility function that values the $10 more than the $5, and anThe algorithm A that reasons something like:
