The Environment Interface Standard (EIS) includes a default implementation. EIS is a Java-based interface standard for connecting an arbitrary agent-platform to an arbitrary environment. The interface provides support for managing the connection (e.g., for pausing and terminating an environment) and for interaction between agents and entities that are available in an environment (e.g., bots in a game). An agent that is connected to a controllable entity receives percepts from and can send actions to that entity. Percepts inform the agent about the state of the entity and its environment. Actions tell the entity which actions to perform in its environment.  Several example implementations of environments are available @github.com/eishub.
