Parameters

objective  IObjectiveModelNonAllocating

The objective function, including model, observations, and parameter bounds.

initialGuess  Double

The initial guess values.

lowerBound  NullableDouble

The lower bounds of the parameters. The array must have the same length as the parameter array. Provide null if not needed.

upperBound  NullableDouble

The upper bounds of the parameters. The array must have the same length as the parameter array. Provide null if not needed.

scales  Double

The scales of the parameters. The array must have the same length as the parameter array. Provide null if not needed.

isFixed  Boolean

Array of booleans, which provide which parameters are fixed. Must have the same length as the parameter array. Provide null if not needed.

cancellationToken  CancellationToken

Token to cancel the evaluation

reportChi2Progress  ActionInt32, Double, IReadOnlyListDouble

Event handler that can be used to report the NumberOfIterations and Chi² value achived so far. Can be null

Return Value
