What happens when the probability of either one of the policies is 0 in Importance Sampling?
Very simply, one of the requirements of off-policy RL to converge, is that the behavioral policy $b$ has at least the same support of the target policy $\pi$, thus:
$$
\forall s \in S \forall a \in A \...

What happens when the probability of either one of the policies is 0 in Importance Sampling?
Background: Importance sampling is used in many off-policy RL algorithms when the data is generated with one policy, yet it is being used to update another policy. The policy generating the data is ...
