NonlinearConstraint Constructor (IObjectiveFunction, ExpressionFuncDouble, ConstraintType, Double, ExpressionFuncDouble, Double)

public NonlinearConstraint(
	IObjectiveFunction objective,
	Expression<Func<double>> function,
	ConstraintType shouldBe,
	double value,
	Expression<Func<double[]>> gradient = null,
	double withinTolerance = 1E-08
)

Public Sub New ( 
	objective As IObjectiveFunction,
	function As Expression(Of Func(Of Double)),
	shouldBe As ConstraintType,
	value As Double,
	Optional gradient As Expression(Of Func(Of Double())) = Nothing,
	Optional withinTolerance As Double = 1E-08
)

Parameters

objective

Type: Accord.Math.OptimizationIObjectiveFunction
The objective function to which this constraint refers.

function

Type: System.Linq.ExpressionsExpressionFuncDouble
A lambda expression defining the left hand side of the constraint equation.

shouldBe

Type: Accord.Math.OptimizationConstraintType
How the left hand side of the constraint should be compared to the given value.

value

Type: SystemDouble
The right hand side of the constraint equation.

gradient (Optional)

Type: System.Linq.ExpressionsExpressionFuncDouble
A lambda expression defining the gradient of the function.

withinTolerance (Optional)

Type: SystemDouble
The tolerance for violations of the constraint. Equality constraints should set this to a small positive value. Default is 1e-8.
