public interface SampleModel

Interface for model that can be used to sample a transition from an input state for a given action and can indicate when a state is terminal or not.

Author:

James MacGlashan.

Method Summary

Modifier and Type	Method and Description
EnvironmentOutcome	sample(State s, Action a) Samples a transition from the transition distribution and returns it.
boolean	terminal(State s) Indicates whether a state is a terminal state (i.e., no more action occurs and zero reward received from there on out)

Method Detail

sample

EnvironmentOutcome sample(State s,
                          Action a)

Samples a transition from the transition distribution and returns it.

Parameters:

s - the source state

a - the action taken in the source state

Returns:

and EnvironmentOutcome describing the sampled transition

terminal

boolean terminal(State s)

Indicates whether a state is a terminal state (i.e., no more action occurs and zero reward received from there on out)

Parameters:

s - the input state to test

Returns:

true if the state is a terminal state, false if it is not.
