public class ExperimentState

extends AbstractState

Experiment is a sequence of trial and inter-trial. A trial begin by the presentation of the stimuli and terminates on juice delivery (reward). An inter-trial begins after the juice delivery. (A trial is one time-step longuer tha its delay (for reward delivery).) Trial details: - At t = 0 -> Present stimulus - At t in [1, trial_delay-1] (in setps) -> No signal - At t = trial_delay (in steps) -> Present reward - At t = trial_delay+1 -> == inter-trial at t=0 Inter-trial details - At t in [0, intertrial_delay-1] -> No signal - At t = intertrial_delay -> == trial at t=0 The class getStates uses a combination of clone and doAction. This class does not provided list of actions, since it is not obervable. This is not observable, and thus returns an equivalent observable state.

Method Summary

void	doAction(Action a) Do an action.
Action[]	getActions() Returns the list of available action from the current state.
State[]	getNextStates(Action a) Returns the list state following the current state under a given action.
State[]	getObservableStates() Returns the list state of observable states for the agents.
DataSet	toDataSet() Similar to the toString method, but return state content in the form of a DataSet.
