Detailed Description

Fit a curve through given points.

Here we try to fit a monotonic function through a given set of points with periodic boundary conditions at both sides (x and y).

Constructor & Destructor Documentation

FittingAnneal::FittingAnneal	(	const char *	filename,
		const char *	params = ""
	)			[inline]

params - like BasicAnneal. Addionally filename - curve to be fitted no_of_nodes - Number of points resume_from - File containing a previous run. resample - If we resume from a file. Resample it with that num of points.

References BasicAnneal::std_init().

Member Function Documentation

ostream& FittingAnneal::show_config

(

ostream &

out

)

[inline, virtual]

Show the configuration parameters.

Reimplemented from BasicAnneal.

References BasicAnneal::show_config().

void FittingAnneal::log

(

)

[inline, virtual]

Perfomr a logging action (uses logline) but can be reimplemented in derived classes.

Reimplemented from BasicAnneal.

References BasicAnneal::logline().

bool FittingAnneal::stop

(

)

[inline, virtual]

Returns true when annealing considers to have converged.

Reimplemented from BasicAnneal.

void FittingAnneal::best_found

(

)

[inline, virtual]

This gets called each time anneal finds a new best energy.

Reimplemented from BasicAnneal.

References BasicAnneal::best_found(), and BasicAnneal::update_minmax_step().

float FittingAnneal::energy

(

)

[inline, virtual]

The energy is , where y_i are the sample points, inter is a linear interpolation of the fitted points we currently have.

Reimplemented from BasicAnneal.
