Interface QSourceForSingleAgent

All Known Implementing Classes:

MADynamicProgramming.BackupBasedQSource, QSourceForSingleAgent.HashBackedQSource

public interface QSourceForSingleAgent

And interface for objects that can store and retrive Q-value objects for a specific agent and state and joint action query. The JAQValue returned can have their q datamember directly modified to modify the Q-values stored and retreived in this object. A hash-backed implementation is also provided in this interface definition.
