Define the task and environment
Specify continuous state and action spaces, termination conditions and a shaped reward in a Gymnasium-compatible environment.
Learn continuous-control policies. Assess stability and reward traces.
Continuous-control reinforcement learning trains agents that output continuous-valued actions to control physical systems (for example joint torques or throttle). Key issues include defining a meaningful reward, handling continuous state and action spaces, measuring policy stability over seeds and episodes, and ensuring safe behaviour at deployment time.

Continuous-control reinforcement learning trains agents that output continuous-valued actions to control physical systems (for example joint torques or throttle). Key issues include defining a meaningful reward, handling continuous state and action spaces, measuring policy stability over seeds and episodes, and ensuring safe behaviour at deployment time.
A proposed application: tune a simulated robot-arm controller to automate a pick-and-place subtask. In practice a human operator should remain in the loop for safety and validation; the supplied starter does not implement a deployable controller.
Specify continuous state and action spaces, termination conditions and a shaped reward in a Gymnasium-compatible environment.
Start with a simple policy-gradient or actor-critic method (PPO, DDPG or SAC) and log reward curves across random seeds.
Report average episode return, standard deviation across seeds, episode length distributions and safety-violation counts.
Add action limits, a safety filter or manual override, and telemetry to detect drift or anomalous trajectories.
The supplied starter simulates a discrete multi-armed bandit with four static Bernoulli reward rates and an epsilon-greedy selection rule; it estimates per-action mean rewards online and prints counts and estimated rates.
for step in range(1, 2001):
if rng.random() < epsilon:
action = rng.integers(len(true_reward_rates))
else:
action = int(np.argmax(estimated_values))
reward = 1 if rng.random() < true_reward_rates[action] else 0
action_counts[action] += 1
total_reward += reward
estimated_values[action] += (reward - estimated_values[action]) / action_counts[action]The code is a discrete bandit simulator: it uses no continuous state or action space, no Gymnasium environment, and implements no policy-gradient, actor-critic or simulator-based control algorithm required for continuous control.
Proposed extension: replace the bandit with a Gymnasium continuous-control environment (for example Pendulum-v1 or a custom robot-arm simulation) and train a simple policy-gradient agent (PPO or SAC) to produce continuous actions and logged reward traces.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
