Description of ipopt - GitHub Pages
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. WebThis program contains Ipopt, a l i b r a r y for large-scale nonlinear optimization. Ipopt is released as open source code under the Eclipse Public License (EPL). For more … WebThe following methods are call by Ipopt if the quasi-Newton approximation is selected. ... If the arguments x, lambda, and values are not NULL, then Ipopt expects that the value of the Hessian as calculated from arrays x and lambda are stored in array values (using the same order as used when specifying the sparsity structure). At this call, ... grashof number horizontal plate
