Motivated by practical settings where a ``good enough'' policy suffices, we study an alternate objective of Good Policy Identification (GPI). For a given reward threshold $\\mu_0$, GPI only requires identifying a policy with expected reward in an episode at least $\\mu_0$ if such a policy exists (positive instance), or declaring None if no such policy exists (negative instance).
