AGE-MOEA2 was added here #272.

Have you tested the implementation on these test problems as well?

[apanichella]

I did some tests for constraints problem in the original MATLAB implementation and it worked well. I think that happens when there are not enough points for the derivative.

I am doing some tests to check this. A fix will follow later today :)
