 This is the code-release for the TuRBO algorithm from ***Scalable Global Optimization via Local Bayesian Optimization*** appearing in NeurIPS 2019. This is an implementation for the noise-free case and may not work well if observations are noisy as the center of the trust region should be chosen based on the posterior mean in this case.

 ### Robot pushing
 The original code for the robot pushing problem is available at https://github.com/zi-w/Ensemble-Bayesian-Optimization. We have made the following changes to the code when running our experiments:

+1. We turned off the visualization, which speeds up the function evaluations.
 2. We replaced all instances of ```np.random.normal(0, 0.01)``` by ```np.random.normal(0, 1e-6)``` in ```push_utils.py```. This makes the function close to noise-free. Another option is to average over several evaluations using the original code
 3. We flipped the sign of the objective function to turn this into a minimization problem.

+We use the constraints 0 <= w_i <= 2 for all parameters. We use ```INITIAL_RANDOM = 1500.0``` to make the problem more challenging.
 
 For more information about the logic behind this controller and how to integrate it with ```gym```, take a look at the original heuristic controller source code: https://github.com/openai/gym/blob/master/gym/envs/box2d/lunar_lander.py#L364
