OptimizerMultivariableFunctionEvaluateDerivative Method (Double, Boolean, OptimizerMultivariableFunctionResults, ITrackCalculationProgress)

Evaluates the gradients of this function. The default implementation of this method will numerically compute the gradients. To do that, the value of the function at the variables will be computed. When using the default implementation, the PerturbationValues must be set.

Namespace:  AGI.Foundation.NumericalMethods
Assembly:  AGI.Foundation.Core (in AGI.Foundation.Core.dll) Version: 24.1.418.0 (24.1.418.0)
public virtual OptimizerMultivariableFunctionDerivativeResults EvaluateDerivative(
	double[] variables,
	bool multithreaded,
	OptimizerMultivariableFunctionResults valueResults,
	ITrackCalculationProgress progressTracker


Type: SystemDouble
The values to compute the gradients at.
Type: SystemBoolean
Should the evaluation be done using as many cores as possible.
Type: AGI.Foundation.NumericalMethodsOptimizerMultivariableFunctionResults
The evaluated value of the function at the variables. If this is then this function will be evaluated at the variables as part of the default evaluation of the gradients.
Type: AGI.FoundationITrackCalculationProgress
An optional progress tracker.

Return Value

Type: OptimizerMultivariableFunctionDerivativeResults
The gradients of the cost function, equality constraints, and inequality constraints.
