Member Enumeration Documentation

◆ message_t

enum FullPhysics::CostFunc::message_t

inherited

Enum type for the message generated by the problem.

In general it is very difficult (probably not possible) to develop a general purpose stopping criterion for a general purpose optimization or curve fitting iterative algorithm. The stopping criterion could be very problem dependent. This enumerated type is used to send a message to the solver of a problem, and the iterative solver can optionally take the message into account in deciding how to proceed.

Enumerator
NONE	There are no messages.
SOLVED	The problem is solved.
ERROR	There is an error in the problem.

		blitz::Array< double, 1 > &	g
	)

virtualinherited

The cost function and its gradient together.

This method passes to the caller the evaluated cost function and its gradient at the current set point.

The parameters (the point in the parameter space) must have already been set before calling this method. The parameters are already set if one of the following methods is already called successfully:

Parameters

[out]	c	The cost function value
[out]	g	The gradient vector with size gradient_size()

◆ cost_gradient_x()

virtual void FullPhysics::CostFuncDiff::cost_gradient_x	(	const blitz::Array< double, 1 > &	x,
		double &	c,
		blitz::Array< double, 1 > &	g

Returns: Cost function value

Definition at line 89 of file cost_func.h.

◆ expected_parameter_size()

virtual int FullPhysics::FreudensteinRothNLLSProblem::expected_parameter_size ( ) const

inlinevirtual

Returns the expected size of the parameters.

This method must be reimplemented by the problem class the inherits ProblemState. It is only in the context of an optimization problem that one knows what the size of the parameters (number of the dimensions of the parameter space) is.

This method is intentionally implemented here instead of being left as a pure virtual method. The intention is that the user to be able to create an object of this class or its derived classes for the purpose of preserving an older state of a problem if needed.

Returns: Expected size of parameters

Reimplemented from FullPhysics::ProblemState.

Definition at line 16 of file freudenstein_roth_nlls_problem.h.

◆ gradient_size()

Definition at line 157 of file cost_func_diff.h.

◆ gradient_x()

virtual blitz::Array<double, 1> FullPhysics::CostFuncDiff::gradient_x ( const blitz::Array< double, 1 > & x )

Definition at line 82 of file cost_func_diff.h.

◆ increment_num_cost_evaluations()

virtual void FullPhysics::CostFunc::increment_num_cost_evaluations ( )

inlineprotectedvirtualinherited

Increments (by 1) cost evaluation counter.

The developer of a derived class, where the true cost function evaluation is implemented, must also call this method when the cost function is evaluated.

It is possible to call this method in cost_x() method; however, at this level we do not know when the cost function gets truly evaluated.

The developer of a derived class can save the expensive components of a cost function evaluation and reuse them when cost is inquired and the parameters have not changed. Therefore, she has the options of calling increment_num_cost_evaluations()

any time cost is inquired or
only when cost is truly evaluated.

If X1 and X2 are two different sets of parameters, then after the sequence of method calls

cost_x(X1)
cost_x(X1)
cost_x(X2)
cost_x(X2)

with the first design option mentioned above num_cost_evaluations() will return 4, but with the second option mentioned above num_cost_evaluations() will return 2.

Therefore, in my opinion it was best not to decide when to call this method at this level in CostFunc class.

Definition at line 198 of file cost_func.h.

◆ increment_num_der1_evaluations()

virtual void FullPhysics::CostFuncDiff::increment_num_der1_evaluations ( )

inlineprotectedvirtualinherited

Increments (by 1) gradient evaluation counter.

The developer of a derived class, where the true gradient evaluation is implemented, must also call this method when the gradient (first order derivatives) is evaluated.

It is possible to call this method in gradient_x() method; however, at this level we do not know when the gradient gets truly evaluated.

The developer of a derived class can save the expensive components of the gradient evaluation and reuse them when gradient is inquired and the parameters have not changed. Therefore, she has the options of calling increment_num_der1_evaluations()

If X1 and X2 are two different sets of parameters, then after the sequence of method calls

gradient_x(X1)
gradient_x(X1)
gradient_x(X2)
gradient_x(X2)

with the first design option mentioned above num_der1_evaluations() will return 4, but with the second option mentioned above num_der1_evaluations() will return 2.

Therefore, in my opinion it was best not to decide when to call this method at this level in CostFuncDiff class.

cost_gradient_x() (see CostFuncDiff class)
residual_x()
jacobian_x()

The number of its rows is the same as residual_size().
The number of its columns is the same as ProblemState::expected_parameter_size() or CostFuncDiff::gradient_size()

inlinevirtualinherited

The Jacobian function with parameters.

This method returns a problem generated message. The message is initialized as CostFunc::NONE. The implementation of a problem can optionally set it to other values as needed, and the solver of the problem can optionally take different course of actions for different messages.

void ProblemState::parameters ( const blitz::Array< double, 1 > & x )

virtualinherited

Sets the problem at a new point in the parameter space.

◆ parameters_different()

bool ProblemState::parameters_different ( const blitz::Array< double, 1 > & x ) const

virtualinherited

Checks whether or not new input parameters are different from the current ones.

The methods checks to see whether or not the new input parameters (point in the parameter space) are different from the parameters maintained by the object for which the method is called.

If the size of the input parameters is not equal to the expected size of the parameters (check comments on expected_parameter_size), then the method will throw an exception.

If the object for which the method is called has currently no parameters set, then the method returns true. Otherwise, the method uses some algorithm to figure out when the difference is "big enough" to be considered different. If the method determines that the new input parameters are different from the current parameters, then it returns true, otherwise, it returns false.
