We present several new results about smoothed analysis of multiobjective optimization problems. Motivated by the discrepancy between worst-case analysis and practical experience, this line of research has gained a lot of attention in the last decade. We consider problems in whichdlinear and one arbitrary objective function are to be optimized over a setS⊆ {0, 1}nof feasible solutions. We improve the previously best known bound for the smoothed number of Pareto-optimal solutions toO(n2dφd), where φ denotes the perturbation parameter. Additionally, we show that for any constantcthecth moment of the smoothed number of Pareto-optimal solutions is bounded byO((n2dφd)c). This improves the previously best known bounds significantly.Furthermore, we address the criticism that the perturbations in smoothed analysis destroy the zero-structure of problems by showing that the smoothed number of Pareto-optimal solutions remains polynomially bounded even for zero-preserving perturbations. This broadens the class of problems captured by smoothed analysis and it has consequences for nonlinear objective functions. One corollary of our result is that the smoothed number of Pareto-optimal solutions is polynomially bounded for polynomial objective functions. Our results also extend to integer optimization problems.
