Glpk does not support a warm start for mip, because this feature assumes
saving the entire search tree. However, to reduce the search you can
provide an incumbent solution with the option "--use FILENAME", where
FILENAME is a text file containing any previously found integer feasible
solution in glpk format. (For the format description see the glpk
reference manual, subsection 3.3.8 "glp_read_mip - read MIP solution in
GLPK format.)
