[Help-glpk] access to original LPX struct from within mip_driver()?

[Erik Rantapaa]

Hi,

I am patching version 4.8 so the MIP solver will save intermediate solutions
as it finds them. I am finding that it would be convenient if the MIPTREE
structure that the mip_driver() routine uses had access to the LPX object
containing the original MIP problem. Then record_solution() could just call
lpx_print_mip() to save the newly found solution to a file (after it uses
lpx_put_mip_soln() first.) Otherwise I can't see how record_solution() can
get to the original LPX structure.

Regards,
ER
