Timing Statistics Object

[ingu119]

Hello,
I would like to get the required CPU time in the function TNLP::finalize_solution. Did I understand the changelog correctly that it should be possible via the command ip_data->TimingStats().OverallAlgorithm().StartCpuTime() in the new version (instead of ip_data->cpu_time_start())?
There I run into the problem that IpoptData::TimingStats is not a const function, but the pointer ip_data in finalize_solution is const.
Did I misunderstand something or would it be possible to provide a const function TimingStatistics& TimingStats() const?

Thanks in advance for your help.

StartCpuTime() (or ip_data->cpu_time_start()) gives the time when Ipopt started. To get the elapsed time, use CpuTime() - ipdata->TimingStats().OverallAlgorithm().StartCpuTime(), where CpuTime() is declared in IpUtils.hpp.

That a const variant of TimingStats() was missing is indeed an oversight.
I added this now on the default branch (stable/3.14).
