Detailed Description

Implementation of the real-world logger.

Can be used to log all (or just those that are better than the preceding) solutions with information about objectives, decision variables (optional) and constraints (optional). See observer_rw() for more information on the options. Produces one "txt" file for each problem function, dimension and instance.

Note

This logger can be used with single- and multi-objective problems, but in the multi-objective case, all solutions are always logged.

Function Documentation

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

static

Initializes the rw logger.

Copies all observer field values that are needed after initialization into logger field values for two reasons:

• If the observer is deleted before the suite, the observer is not available anymore when the logger is finalized.
• This reduces function calls.

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

static

Evaluates the function and constraints and outputs the information according to the observer options.

static void logger_rw_free ( void *  stuff )

static

Frees the memory of the given rw logger.
