Error when using projection command
Posted: 02 Feb 2018, 00:31
Hi,
I am trying to perform a "projection" operation on a polytope with 9 0-1 variables and 9 nonnegative continuous variables. This is the set of qualities and inequalities that form the feasible region of a well-known mixed-integer program, which is attached to this message.
To obtain the facets, I run the following commands in polymake:
The first three lines are executed flawlessly, but polymake seems to get stuck with the fourth command; when I run the command, polymake runs for a few minutes and then suddenly it prints the following output, which seems polymake has crashed. Is this because this is probably a large-scale problem for polymake or I am missing something here?

Code: Select all
$m = lp2poly('/Users/test/Documents/Research/SFCNF/PolyMake/fcnf.lp');
$p = new Polytope<Rational>($m);
print $p->N_LATTICE_POINTS;
$q = projection($p, [1, 2, 3, 4, 5, 6, 7, 8, 9]);
I am using polymake 3.1 on iOS 10.13.1. Thank you very much for your help./Applications/polymake.app/Contents/MacOS/polymake.start: line 66: 70837 Killed: 9 $ResourcesDir/polymake/bin/polymake
