Hi,
Attached find a MPS file that produces the following output when I try to
solve it by invoking glpsol 4.9. as follows: glpsol --mps model.mps
lpx_read_mps: reading problem data from `model.mps'...
lpx_read_mps: problem name not specified
lpx_read_mps: 65 rows, 54 columns, 240 non-zeros
lpx_read_mps: 54 integer columns, none of which are binary
lpx_read_mps: 239 cards were read
lpx_simplex: original LP has 65 rows, 54 columns, 240 non-zeros
lpx_simplex: presolved LP has 63 rows, 51 columns, 216 non-zeros
lpx_adv_basis: size of triangular part = 63
0: objval = -2.520000000e+003 infeas = 1.000000000e+000 (0)
29: objval = 8.409999943e+002 infeas = 0.000000000e+000 (0)
* 29: objval = 8.409999943e+002 infeas = 0.000000000e+000 (0)
* 30: objval = 7.689999812e+002 infeas = 6.821210263e-013 (0)
OPTIMAL SOLUTION FOUND
Integer optimization begins...
Objective function is integral
+ 30: mip = not found yet >= -inf (1; 0)

The model works for many different input parameters.
Thanks in advance. Best regards,
