[AMPL 25019] Inquiry Regarding Discrepancy in Solve Time Metrics

Dear AMPL Community,

I hope this email finds you well. I am reaching out to seek clarification regarding some discrepancies I encountered while working with solve time metrics in AMPL.

In my model, I have been monitoring three time metrics: _solve_elapsed_time, _ampl_elapsed_time, and _total_solve_elapsed_time. From my understanding, _solve_elapsed_time represents the solving time, _ampl_elapsed_time represents the time taken for loading into RAM, and _total_solve_elapsed_time is the sum of the two aforementioned times.

However, when I utilized these metrics, I obtained the following values: 317.406, 10.953, and 317.406 respectively. It’s evident that the sum does not align with expectations.

Could you please provide some insight or clarification on why this inconsistency might occur? Any guidance or assistance you could offer would be greatly appreciated.

Thank you very much for your time and assistance.

Best regards,
