Detailed Description

template<typename Sim>
class craam::msen::RandomizedPolicy< Sim >

A randomized policy that chooses actions according to the provided vector of probabilities.

Action probabilities must sum to one for each state.

State must be convertible to a long index; that is must support (explicit) operator long Actions also have to be indexed. See the definition of simulate.

Constructor & Destructor Documentation

RandomizedPolicy()

template<typename Sim >

craam::msen::RandomizedPolicy< Sim >::RandomizedPolicy ( const Sim &  sim, const vector< numvec > &  probabilities, random_device::result_type  seed = random_device{}()  )

inline

Initializes randomized polices, transition probabilities for each state.

The policy is applicable only to simulators that have:

1) At most as many states as probabilities.size() 2) At least as many actions are max(probabilities[i].size() | i)

Parameters

sim	Simulator used with the policy. The reference is retained, the object should not be deleted
probabilities	List of action probabilities for each state
