 <p>The main feature that's missing on cminpack is the possibility to add constraints on variables. Simple boundary constraints should be enough, as implemented in <a href="http://www.alglib.net/optimization/levenbergmarquardt.php">ALGLIB</a> or <a href="http://www.physics.wisc.edu/~craigm/idl/cmpfit.html">MPFIT</a>.<p>
