- Procedure GMP::Column::Freeze(GMP, column, value)
GMP::Column::Freeze freezes a column in
a generated mathematical program at the given value.
GMP::Column::Freeze( GMP, ! (input) a generated mathematical program column, ! (input) a scalar reference or column number value ! (input) a numerical expression )
The procedure returns 1 on success, and 0 otherwise.
The column remains visible in the constraint listing and math program inspector. In addition, it will be retained in solver maintained copies of the generated math program.
GMP::Column::Unfreezeto undo the freezing.
During a call to procedure
GMP::Column::FreezeAIMMS stores the upper and lower bound of the column before the procedure was called. This information is used when procedure
GMP::Column::Unfreezeis called thereafter. This information is not copied by the function
