Hi,<br>
<div class="moz-forward-container"> <br>
the error states that it it did not find the hmetis output files.
I suggest to create a replacement for one of the detector source
files and send it to you privately - this would give us more debug
information.<br>
<br>
Best,<br>

<div>Hi Michael,</div>
<div><br>
</div>
<div>did you install hmetis? In any case, I
recommend to upgrade your SCIPOptSuite to
6.0 which includes GCG 3.0. If hmetis is not
installed problems may persist but it will
be easier to help you out from that fresh
starting point. BTW, there is a release
report coming with the new release, check
the section on GCG to have an impression of
what you can do with the "explore" menu
after detection.<br>

<div>You wrote "If I can get it working, it
will solve many problems." --> we would
be very happy to hear about successes and
failures, application cases or whatever you
do with GCG. Please consider writing us

<div>I am running GCG and I did
the following which is part of
the getting started
documentation for GCG. The
instance loads but detect
