A smarter tournament system in which players are paired with those of similar skill level and everyone competes in every round. More fair than an elimination bracket and more efficient than a round-robin tournament.

A PostgreSQL database stores match results, and a Python module queries the database to rank and pair players. When two players have the same win record, ties are broken by summing the win record of each player's previous opponents.

• Python: Make sure you have python installed. You can check if it is installed by running python --version
• Virtualbox and Vagrant: You can check if it is installed by running vagrant -v

1. Clone the github project with git clone https://github.com/sonnenfeld269/swiss-tournament-db.git
2. Go inside the folder with cd swiss-tournament-db
3. If you already have psql installed then go to step 4, otherwise use vagrant up and then vagrant ssh to start the virtual machine.
4. Use psql command start psql the console and connect to the tournament database with \c tournament.
5. Now you can use any sql commands like SELECT * FROM players; to browse tables or you can play with the db-api in python by changing queries inside tournament.py
