Dear Christiano,<br>
<br>
please have a look at our FAQ, specifically the question <a
moz-do-not-send="true"
href="http://scip.zib.de/doc-6.0.0/html/FAQ.php#scipaslpsolver">Can
I use SCIP as a pure LP solver</a>, that discusses this and also
the limitations of SCIP for pure LPs.<br>
<br>
Happy solving,<br>

<div>Dear SCIP team,<br>
</div>
<div><br>
</div>
<div>How can I get the values of the dual variables when running
SCIP via command line? <br>
</div>
<div><br>
</div>
<div>For instance, I am on Linux Ubuntu and I run, with the
command <b>scip < script.txt</b>, a script.txt file
containing:<br>
</div>
<div><br>
</div>
<div><b>read model.zpl<br>
opt<br>
write statistics model_stats.txt<br>
write solution model_solution.txt<br>
quit</b><br>
</div>
<div><br>
</div>
<div>where model.zpl is just a toy problem:</div>
<div><br>
</div>
<div><b>var x1 >= 0;<br>
var x2 >= 0;<br>
var x3 >= 0;<br>
var x4 >= 0;<br>
<br>
maximize f: 1*x1 + 1*x2;<br>
<br>
subto c1: 2*x1 + 1*x2 + 1*x3 == 2;<br>
subto c2: 1*x1 + 2*x2 + 1*x4 == 2;<br>
</b></div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>Thanks a lot,</div>
<div>Cristiano<br>
