<div class="moz-cite-prefix">Hi Jan and list,<br>
<br>
please note that from the SCIP command line, you would use the
counter emphasis setting <br>
<br>
set emphasis counter<br>
<br>
to disable primal heuristics and separation and some other stuff
that might ruin the counting process for you. You can specify the
counter emphasis setting also in a settings file, e.g., scip.set,
like so:<br>
<br>
# scip.set file content<br>
emphasis:counter<br>
<br>
I am pretty sure that all the interfaces circulating in this
discussion have some way to read in a settings file.<br>
<br>
Happy solution counting,<br>

Hello Jan,<br>
<br>
yes, both the Python and the Java interface support getting all
collected solutions:<br>

<div class="">Many thanks for your swift response. For now, I’ll
try and use a different approach. Nevertheless, I’d rather
stay away from C. Do the Java and Python interfaces support
the collection of multiple solutions?</div>
