Multiobjective optimization problems are a part of everyday life. Sometimes we manage to solve them and other times they prove to be too difficult and we need help solving them. A good approach to solving multiobjective optimization problems are genetic algorithms. In this work we deal with constrained multiobjective problems. First we describe them and their solution - the Pareto front. Then we present genetic algorithms, desribe two of them, NSGA-II and MOEA/D, more in-depth and review existing constraint handling methods, that allow us to adapt existing multiobjective genetic algorithms for constrained multiobjective optimization. Finally we present two multiobjective constrained test problems, use them to test the beforementioned genetic algorithms and two of the constraint handling techniques, and interpret the results.
