LinearConstraintsProjectorTryConvertToBoxConstraints Method

Attempts to convert the current set of linear constraints to simple lower and upper boundary constraints for each parameter.

Namespace: Altaxo.Calc.Optimization
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3618.0 (4.8.3618.0)
Syntax
C#
Copy
public (double?[] , double?[] , bool[]? , double?[]? , bool[]? )? TryConvertToBoxConstraints(
	double tolerance = 1E-12
)

Parameters

tolerance  Double  (Optional)
When determining whether a matrix entry is considered non-zero, this tolerance is used relative to the row norm. This allows for some numerical imprecision in the constraint definitions while still enabling conversion to boundary constraints when appropriate.

Return Value

NullableValueTupleNullableDouble, NullableDouble, Boolean, NullableDouble, Boolean
A tuple containing arrays of nullable doubles representing the lower and upper bounds for each parameter if the constraints can be represented as simple boundaries; otherwise, null if the conversion is not possible.

Implements

IConstraintsProjectorTryConvertToBoxConstraints(Double)
Remarks
The conversion succeeds only if there are no equality constraints and each inequality constraint involves exactly one parameter. If there are no inequality constraints, all parameters are considered unconstrained.
