Constructors

Constructor	Description
`ConjugateGradient(costfunction)` Full Usage: `ConjugateGradient(costfunction)` Parameters: costfunction : `CostFunction` - Nonlinear cost function to minimize.	Constructor for Conjugate Gradient Method. The constructor specifies the costfunction and optionally user specified ending criteria and line search methods. This class began as a port of CG+ by Guanghui Lui, Jorge Nocedal and Richard Waltz to C# costfunction : `CostFunction` Nonlinear cost function to minimize.
`ConjugateGradient(costfunction, endcriteria)` Full Usage: `ConjugateGradient(costfunction, endcriteria)` Parameters: costfunction : `CostFunction` - Nonlinear cost function to minimize. endcriteria : `EndCriteria` - User specified ending criteria.	Constructor for Conjugate Gradient Method. The constructor specifies the costfunction and optionally user specified ending criteria and line search methods. costfunction : `CostFunction` Nonlinear cost function to minimize. endcriteria : `EndCriteria` User specified ending criteria.
`ConjugateGradient(costfunction, endcriteria, lsm)` Full Usage: `ConjugateGradient(costfunction, endcriteria, lsm)` Parameters: costfunction : `CostFunction` - Nonlinear cost function to minimize. endcriteria : `EndCriteria` - User specified ending criteria. lsm : `LineSearchMethod` - User specified line search method, defaults to Secant line search method	Constructor for Conjugate Gradient Method.

Instance members

Instance member	Description
`this.InitializeMethod` Full Usage: `this.InitializeMethod` Parameters: initialvector : `DoubleVector` Modifiers: abstract	Initialize the optimization method The use of this function is intended for testing/debugging purposes only initialvector : `DoubleVector`
`this.IterateMethod` Full Usage: `this.IterateMethod` Modifiers: abstract	Perform a single iteration of the optimization method The use of this function is intended for testing/debugging purposes only
`this.MethodName` Full Usage: `this.MethodName` Returns: `string` Modifiers: abstract	Method Name Returns: `string`
`this.RestartCount` Full Usage: `this.RestartCount`	Number of iterations between restarts. Must be a non-negative number. If 0 is specified then the number of iterations between restart is the number of variables
