   - Start the simulator (execute gamecontroller-gui.jar with either double-click or using the command "java -jar gamecontroller-gui.jar" on the command line).
   - Setup the simulator as shown in this picture:

   - You can use your player as both the first and the second role of the game, just not at the same time.
   - Run the "Main" class in the project. If you added your own agent class, make sure that it is used in the main method of Main.java. You can also execute the "ant run" on the command line, if you have [[http://ant.apache.org/|Ant]] installed. The output of the agent should say "NanoHTTPD is listening on port 4001", which indicates that your agent is ready and waiting for messages to arrive on the specified port.
-  - Now push the "Start" button in the simulator and your agent should get some messages and reply with the actions it wants to execute. At the end, the output of the simulator tells you how many points your agent got: "Game over! results: 0". Those points correspond more or less with negated costs. That is, more points means the solution had lower costs.

At the end, the output of the simulator tells you how many points both players got: "Game over! results: 0 100", the first number is for white and the second for red.
   -  If the output of the simulator contains any line starting with "SEVERE", something is wrong. The two most common problems are the network connection (e.g., due to a firewall) between the simulator and the agent or the agent sending illegal moves.

 For implementing your agent:
   * Add a new class that implements the "Agent" interface. Look at RandomAgent.java to see how this is done.
-  * You have to implement the methods "init" and "nextAction". "init" will be called once at the start and should be used to initialize the agent. You will get the information, which role your agent is playing (white or red) and how much time the agent has for computing each move. "nextAction" gets the previous moves of both players as input and has to return the next action the agent is supposed to execute within the given time limit. "nextAction" is called for every step of the game. If it is not your players turn return "NOOP".

 To create the zip file you just edit the "student" property in the build.xml and call the "zip" target using ant (execute "ant zip" in the directory containing the build.xml).
