dlx v0.2.1

dlx

An implementation of Knuth's Dancing Links algorithm for the exact cover problem.

Usage:

var dlx = require("dlx");
var matrix = [
	[0, 0, 1, 0, 1, 1, 0],
	[1, 0, 0, 1, 0, 0, 1],
	[0, 1, 1, 0, 0, 1, 0],
	[1, 0, 0, 1, 0, 0, 0],
	[0, 1, 0, 0, 0, 0, 1],
	[0, 0, 0, 1, 1, 0, 1],
];

var solutions = dlx.solve(matrix);
// solutions == [[0, 3, 4]];
