Hi i am MazeR, i use your code to learn NSGA-II
your code is very appropriate for learning,
thanks a lot

here's some speed optimization about your code
the features are all same
just change some function to python built-in functions
like random.uniform, index and delete some slice([:]) that not necessary

the speed test on my computer
original about 5.9s
original(without print) about 5.1s
optimization_speed about 3.6s
optimization_speed(without print) about 2.8s

hope you will like : )
