DQED

 
Solves nonlinear least squares problems with linear constraints and simple
bounds using a quadratic-tensor local model. Some problems with nonlinear
constraints can also be solved. Derivatives required. Forward or reverse
communication. (See R.J. Hanson, SIAM J. Sci. Stat. Comput. 7 (1986) pp.
826-834.).
