Fitness limit check in genetic algorithm

Hello All I'm using Genetic algorithm to solve multi objective problem. Like any optimization algorithm the solution should be the minimum of the objective function, but if I want to add a constrain on the minimum value. Assume I have two objectives Y1 and Y2, I want to make the stopping criteria like this

*if Y1<5 and Y2 is the minimum value

stop*

Is it possible?

Thanks in advance

Do you mean you want to ensure Y2 is always greater than Y1?
