Context triple: [Jonathan J. Hunt, contributedTo, Deep Deterministic Policy Gradient algorithm]

• A. Deterministic policy gradient algorithms
  Deterministic policy gradient algorithms are a class of reinforcement learning methods that learn policies with deterministic actions in continuous action spaces by directly optimizing expected returns via gradient-based updates.
• B. DDPG chosen
  DDPG (Deep Deterministic Policy Gradient) is a model-free, off-policy deep reinforcement learning algorithm designed for continuous action spaces, combining ideas from DQN and actor-critic methods.
• C. Deep Q-Learning
  Deep Q-Learning is a reinforcement learning algorithm that uses deep neural networks to approximate Q-values, enabling agents to learn effective policies directly from high-dimensional inputs like raw images.
• D. Proximal Policy Optimization
  Proximal Policy Optimization is a popular reinforcement learning algorithm that improves policy gradient methods by using clipped objective functions to achieve stable and efficient training.
• E. Asynchronous Advantage Actor-Critic
  Asynchronous Advantage Actor-Critic is a deep reinforcement learning algorithm that trains multiple parallel agents to learn both policy and value functions efficiently and stably.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
