Detailed Description

Implementation of two bi-objective suites created by combining two single-objective problems from the bbob suite:

• bbob-biobj contains 55 functions and 6 dimensions
• bbob-biobj-ext contains 55 + 37 functions and 6 dimensions

The 55 functions of the bbob-biobj suite are created by combining any two single-objective bbob functions i,j (where i<j) from a subset of 10 functions.

The first 55 functions of the bbob-biobj-ext suite are the same as in the original bbob-biobj test suite to which 37 functions are added. Those additional functions are constructed by combining all not yet contained in-group combinations (i,j) of single-objective bbob functions i and j such that i<j (i.e. in particular not all combinations (i,i) are included in this bbob-biobj-ext suite), with the exception of the Weierstrass function (f16) for which the optimum is not unique and thus a nadir point is difficult to compute, see http://numbbo.github.io/coco-doc/bbob-biobj/functions/ for details.

Note

See file suite_biobj_utilities.c for the implementation of the bi-objective problems and the handling of new instances.

Function Documentation

static coco_suite_t* coco_suite_allocate ( const char *  suite_name, const size_t  number_of_functions, const size_t  number_of_dimensions, const size_t *  dimensions, const char *  default_instances  )

static

static const char* suite_biobj_get_instances_by_year ( const int  year )

static

Sets the instances associated with years for the bbob-biobj suites.

Note

The instances of the bi-objective suites generally do not changes with years.

static coco_problem_t* suite_biobj_get_problem ( coco_suite_t *  suite, const size_t  function_idx, const size_t  dimension_idx, const size_t  instance_idx  )

static

Returns the problem from the bbob-biobj suite that corresponds to the given parameters.

Parameters

suite	The COCO suite.
function_idx	Index of the function (starting from 0).
dimension_idx	Index of the dimension (starting from 0).
instance_idx	Index of the instance (starting from 0).

Returns

The problem that corresponds to the given parameters.

static coco_suite_t* suite_biobj_initialize ( const char *  suite_name )

static

Sets the dimensions and default instances for the bbob-biobj suites.
