Dear cbc team,
<div class=""><br class="">
</div>
<div class="">my name is Thomas Enge from Berlin Germany. We are a
small (2 persons) start up company (see also <a moz-do-not-send="true" href="http://www.ovovis.de/" class=""></a><a class="moz-txt-link-abbreviated" href="http://www.ovovis.de/">www.ovovis.de</a> and
then About us). We use AMPL + cbc internally to provide a
portfolio optimization service to energy traders. So far we only
ran tests with our potential customers when we detected that cbc
violates the domain definition of variables in the solution for
specific problem settings. Our variables are defined as >= 0,
but the result also produces negative numbers for these
variables. This is the case for version 2.9.4 - 2.9.6. </div>
<div class=""><br class="">
</div>
<div class="">My question is how can we address this issue best to
you ? And is there a way to receive a quick fix or do we need to
wait for the next stable release ? The latter is very important
for us to understand since it effects our go-live date.</div>
<div class=""><br class="">
</div>
<div class="">Thanks in advance for your help</div>
<div class=""><br class="">
</div>
