All version 1 double network reinforcement learning models no longer have setModelParametersArray() and getModelParametersArray() functions. It is replaced with setModelParameters1(), setModelParameters2(), getModelParameters1(), getModelParameters2() functions.
Improved PrioritizedExperienceReplay.
Changed the way how QLearningNeuralNetwork, StateActionRewardStateActionNeuralNetwork, ExpectedStateActionRewardStateActionNeuralNetwork and its variants calculate the loss values internally.
