The ILinearModel type exposes the following members.

Methods

  Name Description
Public method AddGoal Creates an ILinearGoal object and adds it to the goal list in a model.
Public method AddRow(Object, Int32%) Attempts to add a row to the models and returns a value that indicates whether a row is added to a model.
Public method AddRow(Object, SpecialOrderedSetType, Int32%) Attempts to add a row to the model and returns a value that indicates whether a reference row for a special ordered set is added to a model.
Public method AddVariable Returns a value that indicates whether a user variable is added to a model.
Public method ClearGoals Clears all the goals in a model.
Public method GetBasic Returns a value that indicates whether a variable is a basic variable.
Public method GetBounds Returns the bounds for a variable.
Public method GetCoefficient(Int32, Int32) Returns the coefficient of the A matrix in a linear model.
Public method GetCoefficient(Int32, Int32, Int32) Returns the coefficient of the Q matrix on the objective row.
Public method GetGoalFromIndex Returns the goal entry if the row identifier is associated with a goal.
Public method GetIgnoreBounds Returns a value that indicates whether the bounds of a variable are ignored.
Public method GetIndexFromKey Returns an index that corresponds to the specified key.
Public method GetIntegrality Returns a value that indicates whether a variable is an integer variable.
Public method GetKeyFromIndex Returns the key that is associated with a variable index.
Public method GetRowEntries Returns the collection of nonzero variable entries.
Public method GetRowEntryCount Returns the number of nonzero coefficients for the specified row index.
Public method GetRowQuadraticEntries Returns a collection of nonzero variable entries on a quadratic row.
Public method GetSpecialOrderedSetTypeRowIndexes Returns a list of rows for a special ordered set.
Public method GetValue Returns the value that is associated with a variable index.
Public method GetValueState Gets the value state for the variable.
Public method GetVariableEntries Gets a collection of non-zero column entries for the specified column variable index.
Public method GetVariableEntryCount Returns the number of nonzero coefficients for the specified column variable index.
Public method IsGoal(Int32) Returns a value that indicates whether a row identifier is associated with a goal row.
Public method IsGoal(Int32, ILinearGoal%) Returns a value that indicates whether a row identifier is associated with a goal row.
Public method IsQuadraticVariable Returns a value that indicates whether a variable is in any quadratic row.
Public method IsRow Returns a value that indicates whether a variable index is associated with a row.
Public method RemoveGoal Attempts to remove a goal row and returns a value that indicates whether the row is removed successfully.
Public method SetBasic Sets the basic status for a variable.
Public method SetBounds Sets the bounds for a variable.
Public method SetCoefficient(Int32, Int32, Rational) Sets the coefficient of the A matrix in a linear model.
Public method SetCoefficient(Int32, Rational, Int32, Int32) Sets the coefficient of the Q matrix on the objective row.
Public method SetIgnoreBounds Sets a value that specifies whether to ignore or respect the bounds of a variable during a solve process.
Public method SetIntegrality Sets a value that indicates whether a variable is an integer.
Public method SetLowerBound Sets the lower bound of a variable.
Public method SetUpperBound Sets the upper bound of a variable.
Public method SetValue Sets the value of a linear model.
