The IGradientOptimizationMethod type exposes the following members.

Properties

	Name	Description
	Function	Gets or sets the function to be optimized. (Inherited from IFunctionOptimizationMethodTInput, TOutput.)
	Gradient	Gets or sets a function returning the gradient vector of the function to be optimized for a given value of its free parameters. (Inherited from IGradientOptimizationMethodTInput, TOutput.)
	NumberOfVariables	Gets the number of variables (free parameters) in the optimization problem. (Inherited from IOptimizationMethodTInput, TOutput.)
	Solution	Gets the current solution found, the values of the parameters which optimizes the function. (Inherited from IOptimizationMethodTInput, TOutput.)
	Value	Gets the output of the function at the current Solution. (Inherited from IOptimizationMethodTInput, TOutput.)
