Ipopt output
WebJan 26, 2015 · Output is an options.ipopt struct to pass to IPOPT. There are multiple ways of providing values to override the default options. Their precedence and order of application are as follows: With inputs OVERRIDES and FNAME 1. FNAME is called 2. OVERRIDES are applied With inputs OVERRIDES and MPOPT 1. WebIpopt provides a callback that can be used to log the status of the optimization during a solve. It can also be used to terminate the optimization by returning false. Here is an example: using JuMP, Ipopt, Test model = Model (Ipopt.
