Constructor Detail

UniformRandomSARSCollector

public UniformRandomSARSCollector(SADomain 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

UniformRandomSARSCollector

public UniformRandomSARSCollector(java.util.List<ActionType> actionTypes)

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

Parameters:

actionTypes - the action set to use for collecting data.

Method Detail

collectDataFrom

public SARSData collectDataFrom(State s,
                                SampleModel model,
                                int maxSteps,
                                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.

model - the model of the world to use

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

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

Returns:

the resulting dataset with the newly collected data.

collectDataFrom

public SARSData collectDataFrom(Environment env,
                                int maxSteps,
                                SARSData intoDataset)

Description copied from class: SARSCollector

Collects data from an Environment's current state until either the maximum number of steps is taken or a terminal state is reached. 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:

env - the Environment from which data will be collected.

maxSteps - the maximum number of steps to take in the environment.

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

Returns:

the resulting dataset with the newly collected data.
