Ipopt inf_pr
WebAug 22, 2024 · Using option inf_pr_output, you can tell Ipopt to print the violation of the internal NLP to the log, but there is no option to tell Ipopt to get the value for the original NLP as inf_pr in the intermediate callback. However, you should be able to request this value from the IpCQ object passed to the intermediate callback: WebNov 14, 2010 · derivatives are approximated by Ipopt, it is better to do this only in the space of nonlinear variables.The following methods are call by Ipopt if the quasi-Newton approximation is selected. If -1 is returned as number of nonlinear variables, Ipopt assumes that all variables are nonlinear. Otherwise, it calls get_list_of_nonlinear_variables with an …
