Syntax

public class SteepestDescent

The SteepestDescent type exposes the following members.

Constructors

	Name	Description
	SteepestDescent	Constructor

Methods

	Name	Description
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Reset	Reset and prepare for new solve
	Search(Double)	Search for minimum
	Search(Double, Double)	Search for minimum
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Fields

	Name	Description
	DirectionSmoothing	Smoothing of search direction, such that the previous direction is used partly in the current search.
	Iterations	Stored iteration values. Only used when StoreIterations is set.
	MaxFunctionEval	Maximum number of function evaluations
	MaxIter	Maximum number of iterations
	NumFunctionEval	Hold the number of function evaluations for the last solve.
	NumIter	Hold the actual number of iterations for the last solve.
	RelativeDx	The relative change in x to use when calculating gradient numerically.
	StoreIterations	Flag indicating whether iteration vaues should be stored in Iterations
	TolG	Stop criteria. When the steepest descent vector (2-norm) is smaller than TolG, the iteration stops.
	TolX	Stop criteria. When the step-length/change in x (2-norm) is smaller than TolX, the iteration stops.
