Storing the output Gap and other

[Baburam Rijal]

Hello AMPL users,

I am trying to store the MIP gap and time that come with an option outlev=1 in AMPL with Gurobi solver. Could you suggest to this inquiry please?

Thanks.

There isn't any option to have all the gap and timing detail from the Gurobi log returned to params in AMPL. Gurobi just writes the log to standard output. You'll need to redirect it to a file with a command like "solve >gurobi.log;" and then write a little program of your own to extract the needed values.
