Penalty or barrier method

Please specify the number of the problem you want to deal with. You find them
here.
problem number =

Which method you want to use?

	quadratic loss (penalty) function
	log-barrier method

Please specify the amount of intermediate output

	only final results
	display iteration details

Do you want to specify algorithmic parameters yourself?

	Use the defaults values	These are those displayed below
	your own choice:	Epsilon: epsx = Bounds for penalty/barrier parameter ρ: rhomin = rhomax = rhofac = Do you want to use an alternative initial point? use the default initial point specification of the initial point: xstart(1),...,xstart(n) in 0.4,0.8

Do you want a contour plot of the penalty/barrier function?
This is done in the (x(i),x(k)) plane over the rectangle [x(i)-xdecr1,x(i)+xincr1]*[x(k)-xdecr2,x(k)+xincr2],
with the other components of x held at their current (optimal) values.
Of course i < > k !

	no contour plot
	contourplot request	i = k = xdecr1 = xincr1 = xdecr2 = xincr2 =

treatment of bounds:

	The bounds will not be violated in plotting.
	Plot on the given area
