WebDec 19, 2024 · The only case in which JuMP does not pass Hessian matrices by default is if you use multivariate user-defined functions, where Hessians are not supported at all. There’s no need to set the hessian_approximation parameter either way. You can confirm that Ipopt used Hessians by looking at the summary it prints at the end of a solve.

WebThis class maps the traditional NLP into something that is more useful for Ipopt. This class takes care of storing the calculated model results, handles caching, scaling, and (some day) takes care of addition of slacks. Given a NLP. and (invertible diagonal) scaling matrices , , , , this class represents the NLP.
