<p>Hi Alice,<br>
It seems like you tried to use a member function <i>model.concurrentopt() </i>which does not exist, i believe what you are looking for is the
<i>model.solveConcurrent()</i> call.<br>
If you look into the <i></i><b><i>src/pyscipopt/scip.pyx</i></b> you can find all the existing functions for the objects you are using, so for example in your case inside the object is the
<i>class model</i> and you can find the <i>def solveConcurrent(self)</i> function definition inside.<br>
If you have other issues please open an issue over at <a href="https://github.com/scipopt/PySCIPOpt/issues" class="OWAAutoLink" id="LPlnk593846" previewremoved="true">

<b>Betreff:</b> [SCIP] concurrent solving mode in pyscipopt</font>
<div> </div>
</div>
<div>
<div dir="ltr">Hi,
<div><br>
</div>
<div>
<div>I wanted to use the concurrent solving mode in SCIP (the latest version) to solve a MIQP problem. I'm using the pyscipopt library on python.</div>
<div><br>
</div>
<div>I tried with <i>model.concurrentopt() </i>instead of<i> </i><i>model.optimize() </i>to optimize, but it didn't work, the error message was:</div>
<div><font color="#0000ff">AttributeError: 'pyscipopt.scip.Model' object has no attribute 'concurrentopt'</font><br>
</div>
<div><br>
</div>
<div>I read that I need to set up something before being able to use it.</div>
<div>This is my first time with SCIP and I'm not a computer scientist. <br>
</div>
<div>Could you please explain in detail what I need to set up and how I can do it?</div>
<div><br>
</div>
<div>Thank you very much.</div>
<div>Kind regards,</div>
</div>
