wsolverjs - JavaScript linear programming solver

Version: 0.1.0

The solver supports the following methods:

• brute-force
• simplex
• interior-point methods)

Usage

In standard form

	let {solveLpSimplex, Matrix, Vector} = require('wsolverjs');

	let A = Matrix.init([
		[ 0, 1, 0, 0, 1, 0, 0],
		[-1, 1, 0, 0, 0, 1, 0],
		[ 1, 0,-1,-1, 0, 0, 1],
		[ 0,-1, 1, 1, 0, 0, 0],
	]);
	let b = Vector.init([2,0,-6,6]);
	let c = Vector.init([-1,4,9,9,0,0,0])
	let x = solveLpBrute(c,A,b);

Solve the problem from MPS file

	let {LpMps} = require('wsolverjs');

	LpMps.read('prob1.mps').then(function(p) {
		let g = p.solve();
	});
