Udacity - implementation of a Swiss-system tournament

The goal of the Swiss pairings system is to pair each player with an opponent who has won the same number of matches, or as close as possible.

If you want to run the program you have to have Python ~2.7 and PostgreSQL installed on your machine.

For an initial set up please follow these 3 steps:

1. Install Vagrant and VirtualBox.

2. Clone the fullstack-nanodegree-vm repository.

3. Inside the vagrant folder from the above-mentioned repository, replace the files inside the tournament folder with the files you can find in this present repository - Github Link.

Launch the Vagrant VM from inside the vagrant folder with:

vagrant up

vagrant ssh

Execute the following commands to create the necessary tables inside the database:

cd /vagrant/tournament

psql tournament

\i tournament.sql

Execute the following command to run the test and see the output from your console:

python tournament_test.py

• Prevent rematches between players.

• Don’t assume an even number of players. If there is an odd number of players, assign one player a “bye” (skipped round). A bye counts as a free win. A player should not receive more than one bye in a tournament.

• Support games where a draw (tied game) is possible. This will require changing the arguments to reportMatch.

In order to check if extra credits were achieved, the test suite implements the simulation of:

1. A tournament with an odd number of enrolled players.
2. A tournament with an even number of enrolled players.

Where, in both cases, tied games are allowed, players can't rematch among each other, players can't receive more than 1 Bye-round each.
