WebMay 16, 2024 · This is done in the list out. The first time get_reverse () is called everything works fine. But when I create the function. ca.Function (name, nominal_in + nominal_out + adj_seed, callback.call (nominal_in + adj_seed), inames, onames) It seems that get_reverse () is called a second time. 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.
