Apparently these are very nice and fast

Just in case this helps, yeah SYMPHONY is faster than GLPK AFAIK. Also, @mstrimas wrote a few blogs posts a while ago exploring ILP solvers in R (http://strimas.com/prioritization/ilp-field-guide/, http://strimas.com/prioritization/scip-performance/, http://strimas.com/prioritization/ilp-performance/). Also, lpsymphony (on Bioconductor) can use multiple threads to solve problems (whereas Rsymphony only uses a single thread AFAIK). Note that both Rsymphony and lpsymphony both use the SYMPHONY ILP software to solve problems, they are just different R interfaces (though different SYMPHONY versions may be shipped with CRAN vs. Bioconductor binaries).
