[{"publication":"Journal of Mathematical Analysis and Applications","abstract":[{"text":"In this paper we introduce, in a Hilbert space setting, a second order dynamical system with asymptotically vanishing damping and vanishing Tikhonov regularization that approaches a multiobjective optimization problem with convex and differentiable components of the objective function. Trajectory solutions are shown to exist in finite dimensions. We prove fast convergence of the function values, quantified in terms of a merit function. Based on the regime considered, we establish both weak and, in some cases, strong convergence of trajectory solutions toward a weak Pareto optimal solution. To achieve this, we apply Tikhonov regularization individually to each component of the objective function. This work extends results from single objective convex optimization into the multiobjective setting.","lang":"eng"}],"file":[{"creator":"sonntagk","date_created":"2024-11-28T08:58:00Z","date_updated":"2024-11-28T08:58:00Z","relation":"main_file","file_size":4291134,"access_level":"open_access","file_name":"Inertial dynamics with vanishing Tikhonov regularization for multobjective optimization.pdf","content_type":"application/pdf","file_id":"57473"}],"date_created":"2024-11-28T08:58:17Z","type":"journal_article","keyword":["Pareto optimization","Lyapunov analysis","gradient-like dynamical systems","inertial dynamics","asymptotic vanishing damping","Tikhonov regularization","strong convergence"],"department":[{"_id":"101"},{"_id":"530"},{"_id":"655"}],"title":"Inertial dynamics with vanishing Tikhonov regularization for multobjective optimization","year":"2025","author":[{"last_name":"Bot","first_name":"Radu Ioan","full_name":"Bot, Radu Ioan"},{"id":"56399","first_name":"Konstantin","last_name":"Sonntag","orcid":"https://orcid.org/0000-0003-3384-3496","full_name":"Sonntag, Konstantin"}],"date_updated":"2025-10-16T11:56:36Z","main_file_link":[{"url":"https://arxiv.org/pdf/2411.18422"}],"language":[{"iso":"eng"}],"file_date_updated":"2024-11-28T08:58:00Z","citation":{"ama":"Bot RI, Sonntag K.

Attouch and G. Garrigos, Multiobjective Optimization: An Inertial Dynamical Approach to Pareto Optima, preprint, arXiv:1506.02823, 2015]. We prove existence of solutions to this system in finite dimensions and further prove that its bounded solutions converge weakly to weakly Pareto optimal points.
