Very promising project, but unfortunately not updated and the website has disappeared. It's the most straightforward and unintrusive reinforcement learning framework I've used in Java, though. It was easy to create an agent and run it in an existing environment I've been using to test different agents. The other project I tried recently -- Teachingbox -- required what seemed like a huge investment of time to redesign the test environment so that it fits into their framework.
It seems like you've got a really great framework here! I hope you update your site soon with more examples and newer source code! I can't find any of the source code for your examples.
Nice work ! Great project.
