Hi,

I’m using epsilon constraint method to solve three objective functions. The code runs fine but it stops randomly halfway through execution. I am wondering where is the problem.

Hi,

What do you mean with

it stops randomly halfway through execution

Can you share the log/lst?
For me it seems to work fine and terminates nicely

Hi Fred,

I’m only can obtain one result in gdx. file. I guess it suppose to have a set of pareto optimal solutions?

Hi Jun Keat,

There are different gdx file created. soleps.gdx seems to have the information you are looking for.

Hi Fred,

This is the result I obtained. Seems like the code just stop after getting one solution.

The screenshot indicates that the job was not yet completed. Otherwise you would see

*** Status: Normal completion

in the log (or some error message if there are any issues).
Can you please share the full log file?

Best,
Fred

Yes, as the program stops halfway where my last screenshot shows so I cannot get the logfile.
