Public Member Functions
	OptimizerTargetFunc (GMatrix *pIn, GMatrix *pOut, GFunction *pFunc, GFunctionParser *pParser)
virtual	~OptimizerTargetFunc ()
virtual double	computeError (const GVec &pVector)
	Computes the error of the given vector using all patterns. More...
virtual void	initVector (GVec &pVector)
	Sets pVector to an initial guess. The default behavior is to initialize the vector to all zeros. You should override this method if different behavior is desired. More...
virtual bool	isConstrained ()
virtual bool	isStable ()
	This method should return true if computeError is deterministic with respect to the vector being optimized. It should return false if the error depends on some state other than the vector being optimized. This mostly affects whether the optimization algorithms are permitted to remember old error values for efficiency purposes. Stable is assumed, so you should override this method if your target function is not stable. More...

	Returns a (smart) pointer to the relation, which specifies the type (discrete or real) of each element in the vector that is being optimized. More...

This method should return true if computeError is deterministic with respect to the vector being optimized. It should return false if the error depends on some state other than the vector being optimized. This mostly affects whether the optimization algorithms are permitted to remember old error values for efficiency purposes. Stable is assumed, so you should override this method if your target function is not stable.
