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.

template<typename BP >

double AIToolbox::Factored::MDP::BanditPolicyAdaptor< BP >::getActionProbability ( const State &  s, const Action &  a  ) const

overridevirtual

This function returns the probability of taking the specified action.

Parameters

s	The unused selected state.
a	The selected action.

Returns

The probability of taking the selected action in the specified state.

sampleAction()

template<typename BP >

Action AIToolbox::Factored::MDP::BanditPolicyAdaptor< BP >::sampleAction ( const State &  s ) const

overridevirtual

This function chooses a random action using the underlying bandit policy.

Parameters

s	The unused sampled state of the policy.

Returns

The chosen action.
