Terminate extensive form with --solver-options="mipgap or TimeLimit"

[Abodh Poudyal]

Hello,

I want to terminate the extensive form in PySP after a certain value or gap is reached. I want to get the solution for that particular threshold.

This is what I wrote:

runef -m Reference_Model.py --solver=gurobi --solve --solution-writer=pyomo.pysp.plugins.csvsolutionwriter --solver-options="mipgap=0.0003 TimeLimit=300"

However, I get the following error message:
  File "...\ef_writer_script.py", line 513, in solve

raise RuntimeError(msg)
RuntimeError: EF solve failed solution status check:
Solver Status: aborted
Termination Condition: maxTimeLimit
Solution Status: stoppedByLimit

This works for runph as I can successfully get the CSV file after the simulation terminates. However, I am not able to generate the solution file "ef.csv" using --solver-options due to the error above. 

In my problem, the extensive form is kind of stuck at 0.09% gap for over 9 hours and I want to access the solution at this point.

I would really appreciate any help with this. Thank you.

Regards,
Abodh

I figured I can just comment out raise RuntimeError(msg) part on the  "ef_writer_script.py" file. Looks like I was not paying attention to the error message. Anyway, I would really appreciate it if anyone has some other ideas here.

I think the only thing you can do is set the mipgap to 0.001 (since 0.09% is 0.0009). I realize that is not really want you want.
