+
+
+
+The above diagram represents the flow of control between different objects/classes in the program. It starts with the main program sending the state, action, reward, and next_state to the ReplayBuffer object. Then, the DDPG object selects an action based on the current state and sends it to the gym environment to get the next state and reward.
+
+
+
+Next, the DDPG object samples a batch of transitions from the ReplayBuffer object and uses them to compute the critic loss and actor loss using GradientTape. The GradientTape object computes the gradients of the loss functions with respect to the trainable variables of the critic and actor models.
+
+
+
+After that, the actor_optimizer and critic_optimizer objects apply the gradients to update the actor and critic models' weights. Finally, the DDPG object updates the target networks using a soft update strategy.
+
+
+
+In the end, the episode reward is sent back to the main program.
