Currently such a feature is not supported.

In principle, yes. You can trace each new node of the tree in the
the callback routine specifying it in the parameter list passed to
glp_intopt. For more details please see the glpk reference manual
included in the distribution.

Another way is to patch the glpk source code (see the routine
ios_driver in file src/glpios03.c). See also the BAK package
developed by Brady Hunsaker, which allows visualizing the search
tree for three mip solvers including glpk:
