deterministicTransition

public static java.util.List<StateTransitionProb> deterministicTransition(SampleStateModel model,
                                                                          State s,
                                                                          Action a)

Method to easily implement the FullStateModel.stateTransitions(State, Action) method for deterministic domains. Operates by getting a transition from the SampleStateModel.sample(State, Action) method and wraps it in a StateTransitionProb with probability 1 and then returns a list of that just one element.

Parameters:

model - the SampleStateModel with an implemented SampleStateModel.sample(State, Action) method.

s - the input state

a - the action taken.

Returns:

a List consisting of the single deterministic StateTransitionProb

sampleByEnumeration

public static State sampleByEnumeration(FullStateModel model,
                                        State s,
                                        Action a)

Method to implement the SampleStateModel.sample(State, Action) method when the FullStateModel.stateTransitions(State, Action) method is implemented. Operates by calling the FullStateModel.stateTransitions(State, Action) method, rolls a random number, and selects a transition according the probability specified by FullStateModel.stateTransitions(State, Action).

Parameters:

model - the FullStateModel with the implemented FullStateModel.stateTransitions(State, Action) method.

s - the input state

a - the action to be applied in the input state

Returns:

a sampled state transition (State).
