What would happen if i add cols in a callback when the reason for
calling the calback is GLP_IROWGEN, it would start adding columns to
the global problem?.
To represent subproblems, i.e. nodes of the search tree, the glpk mip
solver uses the original problem object (glp_prob) passed to it from
Thanks, another question, can you get the final branch and bound tree after the
mip is solved?, i could add columns in each node and then add to the initial
relaxation and re-optimize.

The glpk mip solver does not keep fathomed nodes, so if the mip is
solved (to optimality), the final tree is
