Problem:    
Rows:       1
Columns:    2 (2 integer, 0 binary)
Non-zeros:  2
Status:     INTEGER UNDEFINED
Objective:  obj = 0 (MAXimum)

   No.   Row name        Activity     Lower bound   Upper bound
------ ------------    ------------- ------------- -------------
     1 c1                          0             0               

   No. Column name       Activity     Lower bound   Upper bound
------ ------------    ------------- ------------- -------------
     1 x            *              0             1               
     2 y            *              0             0               

Integer feasibility conditions:

KKT.PE: max.abs.err = 0.00e+00 on row 0
        max.rel.err = 0.00e+00 on row 0
        High quality

KKT.PB: max.abs.err = 1.00e+00 on column 1
        max.rel.err = 5.00e-01 on column 1
        SOLUTION IS INFEASIBLE
