Can anybody tell me "world" in code and Readme?
I cannot find where is "world"

` int actionId = agent.selectAction().getIndex();
System.out.println("Agent does action-" + actionId);

        int newStateId = world.update(agent, actionId);
        double reward = world.reward(agent);`

Thanks a lot!

World isn't defined.

Because it is up to you to define it

World means the environment
