Details:
Hello,
it would be useful to add some control parameters to enable the MIP presolver
and integer cuts to glpk(). These correspond to the following options of the
"glpsol" command line solver:
--intopt use MIP presolver (default)
...
--gomory generate Gomory's mixed integer cuts
--mir generate MIR (mixed integer rounding) cuts
--cover generate mixed cover cuts
--clique generate clique cuts
--cuts generate all cuts above
Notice that the MIP presolver is enabled by default so it would be useful to
make it the default also in glpk() to get consistent results between glpk()
and the command line solver.
Thanks in advance, and keep up with the excellent work.
Bye,
Denis Sbragion
