Tic Tac Toe

Let's make a Soar agent play tic tac toe!

Soar agents aren't very interesting unless they can interact with the outside world, so we've provided a game for it to interact with.

Running the game

To run the game server, just execute:

$ ./ttt-server

This will launch a web server. Point your browser at localhost:8000, and you'll be able to play the game. When your agent makes moves, they will be reflected here.

You can change the address and port of the game server by passing command line options. Run with the -h flag for more information.

Running the agent

We've provided an API for interacting with the game server. Look at ./tic_tac_toe.h for details - it's a fairly simple interface.

We've also provided a starter program and a Makefile that exercises the game's API. With the server running, execute the following:

$ sudo apt-get update
$ sudo apt-get install make pkg-config libcurl4-gnutls-dev libjson-c-dev
$ make
$ ./ttt-agent

If everything worked correctly, the starter program should make a hardcoded move, which will be reflected on the board in your web browser.

The tic-tac-toe API needs to know the address and port of the game server. If you are not using the defaults, you can configure these by setting the TTT_ADDRESS and TTT_PORT environment variables respectively.

Your challenge

In order to make a Soar agent play tic-tac-toe, you'll need to:

• Design an agent that can play tic-tac-toe.
• Modify the Makefile to compile and link Soar.
• Design the structure of input- and output-links.
• Use the API in tic_tac_toe.h to query the game state and update the input-link.
• Handle your agent's outputs and use the game's API to affect the game.
