    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="">

                  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 href="http://www.ovovis.de/" target="_blank" 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
