Probably both due to stronger probing.<br>
<br>
Thanks for pointing out debug writing of infeas.mps. Left in by
mistake - I have updated svn stable<br>

cbc-ers,
<div><br>
</div>
<div>Today we updated our cbc library from 2.8-stable to
2.9-stable. We noticed that by using the cbcMain0 and cbcMain1
methods the solve process for 'simple' cases took a few
seconds extra, and for 'strong' problems, the solve performed
better (better integer solutions on solve timeout). Is this
caused by additional heuristics which are enabled by default?</div>
<div><br>
</div>
<div>Also during the solve, a file named infeas.mps was written
to the working directory. Is there a flag we can use in
cbcMain such that this debug information will not be written.</div>
<div><br>

<div>Thanks for your help,</div>
<div>Kind regards,</div>
