Hi,

I am not clear about the second array returned by the get_problem('osy')?? What is it?

from pymoo.problems import get_problem
problem = get_problem("osy")
res = problem.evaluate(X)
print(res[0])   # two columns of results of the osy objective functions
print(res[1])   # what is this???

These are the constraint values (becaues the problem is constrained).
