CONOPT: A Large-Scale GRG Code

Arne Stolbjerg Drud

ORSA Journal on Computing 6(2):207–216, 1994 

As Arne notes in [1], he is helped a bit by the fact that CONOPT users may want to cite a published paper (and because there is no newer successor paper). Still, this is quite an achievement. 

My impression is that large-scale non-linear programming is a little bit under the radar compared to the large number of papers published on linear and mixed-integer programming. Furthermore, CONOPT is a bit under the radar compared to famous academic large-scale NLP solvers such as MINOS and IPOPT. This is opposed to practical use, where CONOPT plays a very important role. It is usually my go-to NLP solver.
