There are two general approaches you can take:

1. Add a penalty clause to your fitness function that suddenly goes up dramatically when the circle leaves the allowed region.
2. Add some logic to GH which always projects the circle back into the orange region, even if Galapagos moves it out.

It's hard to say which is better, though I'd always try and make #2 work first. Anything that doesn't complicate the solver is good news.

I can do the penalty clause thing. But the number of possibilities would still be the same.

I want to decrease the number of possible solutions before even starting the solver. 

What kind of logic do you suggest in your second point?
