bmkfcn

A MATLAB toolkit of benchmark functions for numerical experiments of optimization.

Usage: bmkfcn.m

Get function handles of the benchmark function using index.

[J, lmt, name] = bmkfcn(index,d)

inputs:

• index - integer
• d - demension of benchmark functions

outputs:

• J - function handle, calculating the fitness of x (an d-by-n matrix)
• lmt - constraints
• name - char, function name

example

>> i = 2;
>> d = 4; 
>> [J,lmt,name] =  bmkfcn(i,d)

J = 
  function_handle with value:
    @(x) sum(abs(x))+prod(abs(x))

lmt = 
    -32 32
    -32 32
    -32 32
    -32 32

name = 
    'Schwefel-2.22'

>> n = 10;
>> x = rand(d,n).*(lmt(:,2)-lmt(:,1)) + lmt(:,1);
>> f = J(x)
