Thanks Xypron for the quick answer!

The content of foo.run could have: (I send attached a file as an
example)

 

1.     All printf functions (separating it from the model file and
setting the extensions .txt, .xls …etc without need to set these
parameters on model file) as the example below:

 

From: (param Finance, symbolic, default " Finance.txt";)

To: ( >>Finance.txt) at the end of each printf line.

 

2.     All Glpk run parameters available on glpsol --help:

 

3.     And a functionality to solve different random problems setting
parameters for loopping commands (using param, let, reset and solve
commands) for robust or stochastic optimization besides the model and
data (glpsol -m mymodel.mod -d mydata.dat) calls.

 

As presented in the AMPL link:  

http://www.ampl.com/FAQ/#HowdoIsolveaseriesofdifferentrandomproblemswithdatadrawnfromthesamedistribution

 

param nruns := 5;

        param optvalue {1..nruns};

       for {k in 1..nruns} {

           reset data avail;

           solve;

           let optvalue[k] := total_profit;

        }

        display (sum {k in 1..nruns} optvalue[k]) / nruns;

Dear João,

what should be the content of foo.run?

Would it be more than a trivial shell script:

#!/bin/sh
glpsol -m mymodel.mod -d mydata.mod

Please, describe the value added.

Best regards

Xypron

> Hi,
> Why Glpk doesn't have a script file for running models as CPLEX or
Gurobi?
