// Create a tournament

Run Functional Tests

vendor/bin/phpunit tests


This is a work in progress, and tree creation might be very complex, so there is a bunch of things to achieve.

  • Seed fighter
  • Manage more than 1 fighter out of preliminary round
  • Modify Preliminary Round generation on the fly
  • Use any number of area ( restricted to 1,2,4,8)
  • Manage n+1 case : When for instance, there is 17 competitors in a direct elimination tree, there will have 15 BYES. We can improve that making the first match with 3 competitors.
  • Double elimination
