<p>Hi there,</p>
<p>I'm working on a branch-and-price approach using SCIP
Optimitation Suite 7.0.3 on windows (and on linux, as well). After
the problem is solved, in method SCIPfree (more precisely, method
varFree) I get the following problem:</p>
<p><b><font face="monospace">Assertion failed: (*var)->probindex
== -1, file <my path>\scip\var.c, line 2682</font></b></p>
<p>since the value of probindex is 16. Can you help me to fix this
issue? As I see, the problem already occures when the first priced
variable is going to be freed </p>
<p>I have already checked previous reports about this problem
(<a class="moz-txt-link-freetext" href="http://listserv.zib.de/pipermail/scip/2017-April/003078.html">http://listserv.zib.de/pipermail/scip/2017-April/003078.html</a>).
Briefly stated, I use the following steps to create and add priced
variables to the problem (actually, initial variables are added to
the problem in the same way):</p>
<p><font face="monospace">...<br>
SCIPcreateObjVar( scip, &var, varname, 0.0, 1.0, obj,
SCIP_VARTYPE_BINARY, initial, FALSE, vardata, TRUE )<br>
if( initial )<br>
SCIP_CALL( SCIPaddVar( scip, var ) );<br>
else<br>
SCIP_CALL( SCIPaddPricedVar( scip, var, 1.0 ) );<br>
SCIPchgVarUbLazy( scip, var, 1.0 )<br>
SCIPaddCoefLinear(...)<br>
...<br>
SCIPaddCoefLinear(...)<br>
SCIPreleaseVar( scip, &var )</font></p>
<p>(Note that assertion (*var)->nuses == 0 does not failed).</p>
<p>Best Regards,<br>
Marko<br>
