We are a small (2 persons) start up company (see also <a href="http://www.ovovis.de" class="">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><div class="">Thomas Enge</div><br class=""><br class=""><div apple-content-edited="true" class="">
