Description copied from interface: FullStateModel

Returns the set of possible transitions when Action is applied in State s. The returned list only needs to include transitions that have non-zero probability of occurring.

Specified by:

stateTransitions in interface FullStateModel

Parameters:

s - the source state

a - the action to be applied in the source state

Returns:

the probability distribution of the state transition function specified as a list of StateTransitionProb objects.

sample

public State sample(State s,
                    Action a)

Description copied from interface: SampleStateModel

Samples and returns a State from a state transition function.

Specified by:

sample in interface SampleStateModel

Parameters:

s - the source state

a - the action to be executed in the source state

Returns:

a sample State
