Limitations

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

Troubleshooting

Specified key was too long error

For those running MariaDB or older versions of MySQL you may hit this error when trying to run migrations: As outlined in the Migrations guide to fix this all you have to do is edit your AppServiceProvider.php file and inside the boot method set a default string length:

use Illuminate\Support\Facades\Schema;

public function boot()
{
Schema::defaultStringLength(191);
}

With this configuration, you must have at least...

This error means you don't have enough competitors / teams to create given tree Try to increase competitor number, decrease areas or preliminary group size, if preliminary round is active
