Hi Yves,<br>
<br>
Could you please send me your problem file (LP or MPS) ?<br>
<br>
Since there are other reports of problems with MIPStart maybe there
is some bug.<br>
<br>
Cheers<br>

Just a simple question (surely stupid...).<br>
The solver generates an integer solution file from a very basic
constraint file.<br>
Then I re-compile the same constraint file with the previous
solution file as mipsart argument. And cbc claims:<br>
<br>
[...]<br>
<i>will open mipstart file ./bug_gen.sol.</i><i><br>
</i><i>mipstart values read for 3 variables.</i><i><br>
[...]<br>

be used to build a solution.</small><br>
<small>Cbc0045I Trying just fixing integer variables.<br>
Cbc0045I mipstart provided solution with cost 127.464<br>
[..]</small><br>
<br>
</i><small>What does mean the warning?<br>
Is there something i miss.<br>
<br>
Thanks<br>
<br>
Yves<br>
