Dear SCIP team,
How can I get the values of the dual variables when running SCIP via
command line?
For instance, I am on Linux Ubuntu and I run, with the command *scip <
script.txt*, a script.txt file containing:
*read model.zploptwrite statistics model_stats.txtwrite solution
model_solution.txtquit*
where model.zpl is just a toy problem:
*var x1 >= 0;var x2 >= 0;var x3 >= 0;var x4 >= 0;maximize f: 1*x1 +
1*x2;subto c1: 2*x1 + 1*x2 + 1*x3 == 2;subto c2: 1*x1 +
2*x2 + 1*x4 == 2;*
Is there a simple way to get the values of the dual variables of this
simple example? The statistics and solution files don't seem to have it.
Thanks a lot,
Cristiano
