Hi,

does anyone know where the examples for RL4J are? And is there any documentation for RL4J?

As pointed out [in this Post](https://community.konduit.ai/t/migrating-rl4j-to-dl4j-contrib/1792) the code has moved temporarily. There are some examples [in the Repo](https://github.com/kgoderis/deeplearning4j/tree/rl4j-refactor/rl4j/src/main/java/org/deeplearning4j/rl4j/examples)

Is it currently possible to run the examples without building the dependencies from the refactor-branch? I have tried to compile **NStepRnnExample** using rl4j-cor-1.0.0-M1.1.jar, but I am missing some classes like SteppingAgent and LearningAgent.

To answer my own question: An older version of the example class compiles fine with 1.0.0-M1.1:

It’s also nice to compare the two versions of the example to see the refactoring results.

@hhauschild we’ve retired rl4j. You’re welcome to use it in its oldest version but we won’t have anymore updates for it.
