suite_bbob_mixint.c File Reference

Implementation of a suite with mixed-integer bbob problems. The functions are the same as those in the bbob suite with 24 functions, but the large-scale implementations of the functions are used instead of the original ones for dimensions over 40. Additionally, the functions are scaled as given by suite_bbob_mixint_scaling_factors. More...

Detailed Description

Implementation of a suite with mixed-integer bbob problems. The functions are the same as those in the bbob suite with 24 functions, but the large-scale implementations of the functions are used instead of the original ones for dimensions over 40. Additionally, the functions are scaled as given by suite_bbob_mixint_scaling_factors.

Function Documentation

static coco_problem_t* coco_get_bbob_mixint_problem ( const size_t  function, const size_t  dimension, const size_t  instance, const coco_get_problem_function_t  coco_get_problem_function  )

static

Creates and returns a mixed-integer bbob problem without needing the actual bbob-mixint suite.

Parameters

function	Function
dimension	Dimension
instance	Instance
coco_get_problem_function	The function that is used to access the continuous problem.

Returns

The problem that corresponds to the given parameters.

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_bbob_mixint_get_instances_by_year ( const int  year )

static

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

static coco_problem_t* suite_bbob_mixint_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-mixint suite that corresponds to the given parameters.

Uses large-scale bbob functions if dimension is equal or larger than the hard-coded dim_large_scale value (50).

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_bbob_mixint_initialize ( const char *  suite_name )

static

Sets the dimensions and default instances for the bbob-mixint suite.
