(Noisy) BBOB 2009 test function generator.
bbob2009_function(dimensions, fid, iid) noisy_bbob2009_function(dimensions, fid, iid, noiseSeed = 1L)
dimensions |
Size of parameter space. |
fid |
Function ID, valid values are 1 to 24. |
iid |
Instance ID, defaults to |
noiseSeed |
Seed for the noise random number
generator, defaults to |
A soo_function
.
Due to the way the instances are generated, the function
value at the optimal parameter settings (as returned by
global_minimum
) may differ slightly from
the optimal function value. These differences are in the
order of 10^{-16}.
Also note that the random number generator used for the noisy test functions is shared by all instanciated test functions. This means that if you run multiple trials in parallel within the same interpreter, your results will not necessarily be repeatable.
