Constructor Detail

SARSCollector.UniformRandomSARSCollector

public SARSCollector.UniformRandomSARSCollector(Domain domain)

Initializes the collector's action set using the actions that are part of the domain.

Parameters:

domain - the domain containing the actions to use

SARSCollector.UniformRandomSARSCollector

public SARSCollector.UniformRandomSARSCollector(java.util.List<Action> actions)

Initializes this collector's action set to use for collecting data.

Method Detail

collectDataFrom

public SARSData collectDataFrom(State s,
                       RewardFunction rf,
                       int maxSteps,
                       TerminalFunction tf,
                       SARSData intoDataset)

Description copied from class: SARSCollector

Collects data from an initial state until either a terminal state is reached or until the maximum number of steps is taken. Data is stored into the dataset intoDataset and returned. If intoDataset is null, then it is first created.

Specified by:

collectDataFrom in class SARSCollector

Parameters:

s - the initial state from which data should be collected.

rf - the reward function from which rewards are tracks.

maxSteps - the maximum number of steps that can be taken.

tf - the terminal function that ends data collection.

intoDataset - the dataset into which data will be stored. If null, a dataset is created.

Returns:

the resulting dataset with the newly collected data.
