Parameters

variables: Type: SystemDouble
The values of the variables to evaluate at.
order: Type: SystemInt32
The highest order of the function that should be evaluated. By default, this can be 0 or 1.
multithreaded: Type: SystemBoolean
Should the evaluation be done using as many cores as possible.
progressTracker: Type: AGI.FoundationITrackCalculationProgress
An optional progress tracker.

Return Value

Type: MultivariableFunctionEvaluationAndDerivativeResultsOptimizerMultivariableFunctionResults, OptimizerMultivariableFunctionDerivativeResults
The cost function value, equality constraint values, inequality constraint values, and gradients of all those values.
