Dear Andrew,
the attached MILP model exits with:
* 5400: objval = 6.264244529e+00 infeas = 0.000000000e+00 (0)
* 5450: objval = 5.968440326e+00 infeas = 0.000000000e+00 (0)
OPTIMAL SOLUTION FOUND
Integer optimization begins...
+ 5450: mip = not found yet >= -inf (1; 0)
+ 5481: >>>>> 6.036226238e+00 >= 5.968440326e+00 1.1% (32; 0)
GLPK internal error: x <= ub; file glpios03.c, line 265
Abort
Maybe it is a scaling problem, but just wanted to let you know in case it
has triggered a bug. I have a very similar model which runs without any
problems.
With best regards
