Detailed Description

Implementation of the bbob logger.

Logs the performance of a single-objective optimizer on noisy or noiseless problems. It produces four kinds of files:

The "info" files ...
The "dat" files ...
The "tdat" files ...
The "rdat" files ...

Function Documentation

static coco_problem_t* logger_bbob	(	coco_observer_t *	observer,
		coco_problem_t *	inner_problem
	)

static

static void logger_bbob_error_io	(	FILE *	path,
		int	errnum
	)

static

Error when trying to create the file "path"

static void logger_bbob_evaluate	(	coco_problem_t *	problem,
		const double *	x,
		double *	y
	)

static

Layer added to the transformed-problem evaluate_function by the logger

static void logger_bbob_free ( void * stuff )

static

Also serves as a finalize run method so. Must be called at the end of Each run to correctly fill the index file

TODO: make sure it is called at the end of each run or move the writing into files to another function

static void logger_bbob_initialize	(	logger_bbob_data_t *	logger,
		coco_problem_t *	inner_problem
	)

static

Generates the different files and folder needed by the logger to store the data if these don't already exist

static void logger_bbob_open_dataFile	(	FILE **	target_file,
		const char *	path,
		const char *	dataFile_path,
		const char *	file_extension
	)

static

Creates the data files or simply opens it

static void logger_bbob_openIndexFile	(	logger_bbob_data_t *	logger,
		const char *	folder_path,
		const char *	indexFile_prefix,
		const char *	function_id,
		const char *	dataFile_path,
		const char *	suite_name
	)

static

Creates the index file fileName_prefix+problem_id+file_extension in folder_path

static void logger_bbob_write_data	(	FILE *	target_file,
		size_t	number_of_f_evaluations,
		size_t	number_of_cons_evaluations,
		double	fvalue,
		double	best_fvalue,
		double	best_value,
		const double *	x,
		size_t	number_of_variables,
		size_t	number_of_integer_variables,
		const double *	constraints,
		size_t	number_of_constraints,
		const int	log_discrete_as_int
	)

static

adds a formated line to a data file

static int single_digit_constraint_value ( const double c )

static

Discretized constraint value, ~8 + log10(c), in a single digit.

-..0 -> 0 0..1e-7 -> 1 1e-7..1e-6 -> 2 ... 1e-1..1 -> 8 >1 -> 9
