[ojAlgo-user] optimizing from a .mps file

[David S. <d.s...@4c...>]

Hello,
I am trying to use ojAlgo to read from a .mps file and use Linear/Mixed
Integer Programming to solve it. Currently the code for this is as follows:

MathProgSysModel mps = MathProgSysModel.makeFromFile(aFile);
OptimisationSolver os = mps.getDefaultSolver();
Result rs = os.solve();

This runs correctly and solves the .mps input file as desired. However the
second line (calling getDefaultSolver()) appears to start an additional
thread running or something, as the java process does not stop after the
rest of my code finishes (but the remaining code after this line does get
executed). Is this intended, and/or am I using it incorrectly and how can I
use it correctly to prevent the java process continuing to be active
indefinitely instead of closing?

Thanks,
David
