<h1>Test cobyla</h1>
This example shows an easy example of nonlinear optimization with JavaScript. Look at the source code! <br>

The point on the unit circle closest to (5,5) is:

<script type="text/javascript">

var n=2; 			// + of variables
var x=new Array(n);
var m=2; 			// number of constraints
var rhobeg = 5.0;	// Various Cobyla constants, see Cobyla docs in Cobyja.js
var rhoend = 1.0e-6;
var iprint = 3;
var maxfun = 3500;
var fmaxiter = 20;

function test(n,m,x,con) {  	// objective function
   con[0]=x[0]*x[0]+x[1]*x[1]-1 		// first inequality constraint
   con[1]=-(x[0]*x[0]+x[1]*x[1]-1)	// second inequality constraint, together an equality constraint
   return (x[0]-5)*(x[0]-5)+(x[1]-5)*(x[1]-5); // objective function
   }
x[0]=-7.9; x[1]=3.2;
var r=FindMinimum(test, n,  m, x, rhobeg, rhoend,  iprint,  maxfun, fmaxiter);
document.write("Result="+x);
