---------------------------+----------------------------------
Sometimes one can use a fast numerical LP solver to solve a problem to
"optimality",
then reconstruct the primal and dual solution in rational arithmetic (or
over whatever base_ring was used...) and in this way prove that this basis
is indeed optimal.
MixedIntegerLinearProgram should support this mode of operation.
#18685 provides the necessary basis-status functions (for the GLPK
backend).
#18688 provides a solver-independent interface to these functions.
