Hi everybody,
There is an error in the attached code, Ma and Mb should be 50, not
90. As additional information, it seems that the solution of the
relaxed program matches the expected optimal solution.
92 rows, 44 columns, 240 non-zeros
0: obj = 0.000000000e+00 infeas = 1.200e+01 (0)
* 31: obj = 2.000000000e+00 infeas = 0.000e+00 (0)
* 32: obj = 2.000000000e+00 infeas = 0.000e+00 (0)
OPTIMAL SOLUTION FOUND
Integer optimization begins...
+ 32: mip = not found yet >= -inf (1; 0)
+ 93: >>>>> 4.000000000e+00 >= 2.000000000e+00 50.0% (13; 28)
+ 2081: mip = 4.000000000e+00 >= tree is empty 0.0% (0; 1585)
INTEGER OPTIMAL SOLUTION FOUND
Regards,
Daniel
