Hi Thomas,<br class="">
<br class="">
I converted your MPS to LP to take a look (don't have AMPL here). <br class="">
Strangely no "bounds" section is generated. <br class="">
<br class="">
The MPS conversion also lost the original names, can yon generate
including the original names so that the specific result for
variable ym is visible ?<br class="">
<br class="">
Cheers<br class="">

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" 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>
<div class="">Thomas Enge</div>
