Originally defined as the task of learning the best possible policy from a fixed set of a prioriknown transition samples, the batch algorithms developed in this field can be easily adapted to the classical online case, where the agent interacts with the environment while learning. As a consequence, learning algorithms are rarely applied on safetycritical systems in the real world.
