Specific gap reach time displaying

Post by baybora » 1 month ago

Hello;

When I was running my gams model, I would like to see the gap reach times on the process log screen, specifically, is it possible to see the gap reach times in the 25th, 50th and 75th seconds or the gap reach percentages in those seconds, which I can set specially.


Thank you in advance for your help.

There is no such general option in GAMS. Some solver links implement the miptrace or solvetrace option (see https://www.gams.com/35/docs/UG_SolverU ... SOLVETRACE) which allows you to create a time series with lower and upper bound (you will need to calculate the gap from this yourself). Please check in the Solver documentation (https://www.gams.com/35/docs/S_MAIN.html) if your solver supports this.
