NonlinearProgramOptions Class

Specifies the methods and numerical controls used to solve a nonlinear program.

public sealed class NonlinearProgramOptions

Public NotInheritable Class NonlinearProgramOptions

C++/CLI

[<SealedAttribute>]
type NonlinearProgramOptions = class end

Inheritance: Object → NonlinearProgramOptions

Remarks

Pass this object to Solve(NonlinearProgramOptions). Each solve takes a private copy before invoking callbacks. Changes affect subsequent solves, not a solve already in progress. Automatic selection writes the concrete choice back to Method unless the caller changes Method during initialization. Set Method to Automatic again to request new selection. Configure an object before sharing it between threads; simultaneous writes are not supported. Derivative functions and initial guesses belong to the model. Iteration and evaluation limits remain on Solver.

Constructors

NonlinearProgramOptions

Creates options with the default nonlinear solver settings.

Properties

CurvatureDampingFactor	Gets or sets the minimum relative curvature retained by a damped quasi-Newton update.
Default	Gets a new options object with the default solver settings.
HistorySize	Gets or sets the number of retained BFGS steps.
Method	Gets or sets the method used to solve the nonlinear program.
OptimalityTolerance	Gets or sets the tolerance used to check constraints and first-order optimality.
PreconditioningMethod	Gets or sets the Newton conjugate-gradient preconditioning method.
SparseCurvatureMethod	Gets or sets the curvature source for sparse nonlinear steps.
UseFeasibilityRestoration	Gets or sets whether sparse optimization can try a short feasibility recovery phase.
UseLineSearch	Gets or sets whether unbounded Newton steps use backtracking.
UseQuadraticProgramWarmStart	Gets or sets whether reduced QP steps reuse active constraints from earlier steps.
UseSecondOrderCorrection	Gets or sets whether sparse optimization corrects steps rejected because of constraint curvature.

Methods

Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetHashCode	Serves as the default hash function. (Inherited from Object)
GetType	Gets the Type of the current instance. (Inherited from Object)
ToString	Returns a string that represents the current object. (Inherited from Object)
