This may be a silly question, but integer linear programming seems to
be about maximizing some quantity relative to constraints given by a

Here are the Singular examples done with Sage:
sage: singular.LIB(intprog.lib)
1. call with single right-hand vector
sage: A = matrix(ZZ, 2, 3,
I believe that the answer is currently: no, Sage cannot do integer
linear programming. But I could be wrong, if that capability is
hiding in something added since the last time this question came up.
I am not sure what open source code is out there to do that - ?

I'm not sure either, but he could try his luck with openopt:

I have created a spkg to install lp_solve into Sage; it can be obtained at:
http://www.math.unl.edu/~shartke2/files/lp_solve-5.5.0.13.spkg
I have posted to sage-devel suggesting this spkg for inclusion into Sage.
lp_solve includes a linear programming solver (simplex based) and an integer

Is this what you are looking for:
