What you did should work. If you can say what version of SYMPHONY you are using and on what platform (OS, compiler, etc), I will look into the origin of the segmentation fault.<br><br>Cheers,<br><br>Ted<br><br><div class="gmail_quote">

Hi,<br>
<br>
I&#39;m using OsiSymSolverInterface and would like to resolve a MILP<br>
problem after right-hand-side modification by using warm starting. But<br>
when I use setWarmStart() and call resolve(), the solver prints:<br>
<br>
&quot;sym_warm_solve(): SYMPHONY can not resolve for the<br>
rhs or column bounds change when cuts exist, for now!&quot;<br>
<br>
I was trying to do setSymParam(&quot;generate_cgl_cuts&quot;, FALSE), but this<br>
leads me to &quot;Segmentation fault&quot;.<br>
<br>
How can I solve this problem?<br>
<br>
Thank you.<br>
