     Using the same learning algorithm, network architecture and hyper-parameters, our algorithm robustly solves more than 20 simulated physics tasks, including classic problems such as cartpole swing-up, dexterous manipulation, legged locomotion and car driving.

Usually used attributively, e.g. in reference to a cartpole system or the cartpole problem.
