Detailed Description

This class represents a random policy.

This class simply returns a random action every time it is polled.

Constructor & Destructor Documentation

RandomPolicy()

AIToolbox::Bandit::RandomPolicy::RandomPolicy

(

size_t

a

)

Basic constructor.

Parameters

a	The number of actions available to the agent.

Member Function Documentation

getActionProbability()

virtual double AIToolbox::Bandit::RandomPolicy::getActionProbability ( const size_t &  a ) const

overridevirtual

This function returns the probability of taking the specified action in the specified state.

Parameters

a	The selected action.

Returns

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

getPolicy()

virtual Vector AIToolbox::Bandit::RandomPolicy::getPolicy ( ) const

overridevirtual

This function returns a vector containing all probabilities of the policy.

Note that this may be expensive to compute, and should not be called often (aside from the fact that it needs to allocate a new Vector each time).

Ideally this function can be called only when there is a repeated need to access the same policy values in an efficient manner.

Implements AIToolbox::Bandit::PolicyInterface.

sampleAction()

virtual size_t AIToolbox::Bandit::RandomPolicy::sampleAction ( ) const

overridevirtual

This function chooses a random action for state s, following the policy distribution.

Returns

The chosen action.
