Detailed Description
template<typename BanditPolicy>
class AIToolbox::Factored::MDP::BanditPolicyAdaptor< BanditPolicy >
This class extends a Bandit policy so that it can be called from MDP code.
This class simply ignores all states that are passed to it, and just uses the actions in order to sample and call the underlying Bandit code.
- Template Parameters
-
BanditPolicy The Bandit policy to wrap.
