Procedure GMP::Column::DeleteRaw(GMP, colSet)

GMP::Column::DeleteRaw

The procedure GMP::Column::DeleteRaw marks a group of columns in a generated mathematical program as deleted.

GMP::Column::DeleteRaw(
     GMP,            ! (input) a generated mathematical program
     colSet          ! (input) a subset of Integers
     )

Arguments

GMP

An element in AllGeneratedMathematicalPrograms.

colSet

A subset of the set Integers, representing a set of column numbers.

Return Value

The procedure returns 1 on success, or 0 otherwise.

Note

• The columns will not be printed in the constraint listing, nor be visible in the Math Program Inspector and they will be removed from any solver maintained copies.

Example

Assume that ‘MP’ is a mathematical program. To use GMP::Column::DeleteRaw we declare the following identifiers (in ams format):

ElementParameter myGMP {
    Range: AllGeneratedMathematicalPrograms;
}
Set VariableSet {
    SubsetOf: AllVariables;
}
Set ColumnSet {
    SubsetOf: Integers;
    Index: cc;
}

To delete the variable x(i) we can use:

myGMP := GMP::Instance::Generate( MP );

VariableSet := { 'x' };
ColumnSet := GMP::Instance::GetColumnNumbers( myGMP, VariableSet );

GMP::Column::DeleteRaw( myGMP, ColumnSet );
