◆ CleanUp()

void operations_research::glop::DataWrapper< MPModelProto >::CleanUp ( )
inline

We detect that the lower bound was not set when it is left to its default value of zero.

Create a new Boolean variable.

Todo
(user): Experiment with the switch constant.

bool_var == 0 implies var == 0.

bool_var == 1 implies lb <= var <= ub

var >= bool_var * lb

var <= bool_var * ub

◆ ConstraintLowerBound()

double operations_research::glop::DataWrapper< MPModelProto >::ConstraintLowerBound ( int row_index)
inline

Definition at line 173 of file mps_reader.cc.

◆ ConstraintUpperBound()

double operations_research::glop::DataWrapper< MPModelProto >::ConstraintUpperBound ( int row_index)
inline

Definition at line 176 of file mps_reader.cc.

◆ CreateIndicatorConstraint()

absl::Status operations_research::glop::DataWrapper< MPModelProto >::CreateIndicatorConstraint ( absl::string_view cst_name,
int var_index,
bool var_value )
inline

Definition at line 211 of file mps_reader.cc.

◆ FindOrCreateConstraint()

int operations_research::glop::DataWrapper< MPModelProto >::FindOrCreateConstraint ( absl::string_view name)
inline

Definition at line 144 of file mps_reader.cc.

◆ FindOrCreateVariable()

int operations_research::glop::DataWrapper< MPModelProto >::FindOrCreateVariable ( absl::string_view name)
inline

Definition at line 180 of file mps_reader.cc.

◆ SetConstraintBounds()

void operations_research::glop::DataWrapper< MPModelProto >::SetConstraintBounds ( int index,
double lower_bound,
double upper_bound )
inline

Definition at line 156 of file mps_reader.cc.

◆ SetConstraintCoefficient()

void operations_research::glop::DataWrapper< MPModelProto >::SetConstraintCoefficient ( int row_index,
int col_index,
double coefficient )
inline
Note
we assume that there is no duplicate in the mps file format. If there is, we will just add more than one entry from the same variable in a constraint, and we let any program that ingests an MPModelProto handle it.
