-Dots and Boxes application
-==========================
-
-Live demo: https://people.cs.kuleuven.be/wannes.meert/dotsandboxes/play
-
-![Screenshot of Dots and Boxes](https://people.cs.kuleuven.be/wannes.meert/dotsandboxes/screenshot.png?v=2)
-
-This setup is part of the course "Machine Learning: Project" (KU Leuven,
-Faculty of engineering, Department of Computer Science,
-[DTAI research group](https://dtai.cs.kuleuven.be)).
-
-
-Installation
-------------
-
-The example agent is designed for Python 3.6 and requires the
-[websockets](https://websockets.readthedocs.io) package. Dependencies can be
-installed using pip:
-
-    $ pip install -r requirements.txt
-
-
-Start the game GUI
-------------------
-
-This program shows a web-based GUI to play the Dots and Boxes
-game. This supports human-human, agent-human and agent-agent combinations.
-It is a simple Javascript based application that runs entirely in the browser.
-You can start it by opening the file `static/dotsandboxes.html` in a browser.
-Or alternatively, you can start the app using the included simple server:
-
-    $ ./dotsandboxesserver.py 8080
-
-The game can then be played by directing your browser to http://127.0.0.1:8080.
-
-
-Start the agent client
-----------------------
-
-This is the program that runs a game-playing agent. This application listens
-to [websocket](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API)
-requests that communicate game information and sends back the next action it
-wants to play.
-
-Starting the agent client is done using the following command:
-
-    $ ./dotsandboxesagent <port>
-
-This starts a websocket on the given port that can receveive JSON messages.
-
-The JSON messages given below should be handled by your agent.
-Take into account the maximal time allowed to reply.
-
-### Initiate the game
-
-Both players get a message that a new game has started:
-
-    {
-        "type": "start",
-        "player": 1,
-        "timelimit", 0.5,
-        "grid": [5, 5],
-        "game": "123456"
-    }
-
-where `player` is the number assigned to this agent, `timelimit` is the
-time in seconds in which you need to send your action back to the server,
-and `grid` is the grid size in rows and columns.
-
-If you are player 1, reply with the first action you want to perform:
-
-    {
-        "type": "action",
-        "location": [1, 1],
-        "orientation": "v"
-    }
-
-The field `location` is expressed as row and column (zero-based numbering) and
-`orientation` is either "v" (vertical) or "h" (horizontal).
-
-
-### Action in the game
-
-When an action is played, the message sent to both players is:
-
-    {
-        "type": "action",
-        "game": "123456",
-        "player": 1,
-        "nextplayer": 2,
-        "score": [0, 0],
-        "location": [1, 1],
-        "orientation": "v"
-    }
-
-
-If it is your turn you should answer with a message that states your next
-move:
-
-    {
-        "type": "action",
-        "location": [1, 1],
-        "orientation": "v"
-    }
-
-
-### Game end
-
-When the game ends after an action, the message is slightly altered:
-
-    {
-        "type": "end",
-        "game": "123456",
-        "player": 1,
-        "nextplayer": 0,
-        "score": [3, 1],
-        "location": [1, 1],
-        "orientation": "v",
-        "winner": 1
-    }
-
-The `type` field becomes `end` and a new field `winner` is set to the player
-that has won the game.
