Re: [Help-glpk] Help using auxiliar variables

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)
