Nonlinear constraint not satisfied for paretosearch

Hi community,

I am using paretosearch for a 2-objective optimization problem to maximize them. Based on hardcoded values, I know objective #2 can be at least c. So I want to make it a constraint that in the constraint function, I specify objective #2 has to be greater than c, which I know it can be achieved. But after I run the algorithm and get the pareto front, there are points on the pareto front whose objective #2 is lower than the constrainted value, why this is the case?

As shown in the attached picture, I already set a constraint that objective #2 has to be greater than . But the pareto front still has the points that are lower than . Why this is the case? Can I not set the constraint this way?

I am setting this constraint in the mindset that I want the solver to explore more in this direction.

Thank you!

We don't know your code - so we cannot comment on your questions.

Maybe you have to set a smaller value for the ConstraintTolerance.
