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. Must have the same length as initialGuess. Provide if not needed.

upperBound  NullableDouble

The upper bounds of the parameters. Must have the same length as initialGuess. Provide if not needed.

scales  Double

The scales of the parameters. Must have the same length as initialGuess. Provide if not needed.

isFixed  Boolean

Array indicating which parameters are fixed. Must have the same length as initialGuess. Provide if not needed.

cancellationToken  CancellationToken

Token to cancel the evaluation.

reportChi2Progress  ActionInt32, Double, IReadOnlyListDouble

Callback used to report the number of iterations, Chi² value, and current parameter set achieved so far. Can be .
