The ROWS section contains the name and type of the rows (linear constraints or objectives). The type of each row is specified
by the indicator code in field1
as follows:
MIN: minimization objective
MAX: maximization objective
N: objective
G: constraint
L: constraint
E: constraint

Notes:
At least one objective row should be specified in the ROWS section. It is possible to specify multiple objective rows. However, among all the data records indicating the objective, only the first one is regarded as the objective row, while the rest are ignored. If a type-N row is taken as the objective row, minimization is assumed.
Duplicate entries of field2
in the ROWS section are not allowed. In other words, row name is unique. The variable field2
in the ROWS section cannot take a missing value.
