Round Robin
A simple round robin tournament match scheduler using the standard scheduling algorithm.
Usage
Simply give the number of players (with an optional players array), and it will spit out the array of rounds necessary:
var robin = require('roundrobin');
robin(6);
[ [ [ 1, 6 ], [ 2, 5 ], [ 3, 4 ] ],
[ [ 5, 1 ], [ 6, 4 ], [ 2, 3 ] ],
[ [ 1, 4 ], [ 5, 3 ], [ 6, 2 ] ],
[ [ 3, 1 ], [ 4, 2 ], [ 5, 6 ] ],
[ [ 1, 2 ], [ 3, 6 ], [ 4, 5 ] ] ]
// or with names supplied
robin(6, ['clux', 'lockjaw', 'pibbz', 'xeno', 'e114', 'eclipse']);
[ [ [ 'clux', 'eclipse' ], [ 'lockjaw', 'e114' ], [ 'pibbz', 'xeno' ] ],
[ [ 'e114', 'clux' ], [ 'eclipse', 'xeno' ], [ 'lockjaw', 'pibbz' ] ],
[ [ 'clux', 'xeno' ], [ 'e114', 'pibbz' ], [ 'eclipse', 'lockjaw' ] ],
[ [ 'pibbz', 'clux', ], [ 'xeno', 'lockjaw' ], [ 'e114', 'eclipse' ] ],
[ [ 'clux', 'lockjaw' ], [ 'pibbz', 'eclipse' ], [ 'xeno', 'e114' ] ] ]Home/Away Matches
