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":[{"content_type":"application/pdf","relation":"main_file","creator":"sonntagk","date_created":"2024-11-28T08:58:00Z","date_updated":"2024-11-28T08:58:00Z","file_id":"57473","file_name":"Inertial dynamics with vanishing Tikhonov regularization for multobjective optimization.pdf","access_level":"open_access","file_size":4291134}],"publication":"Journal of Mathematical Analysis and Applications","keyword":["Pareto optimization","Lyapunov analysis","gradient-like dynamical systems","inertial dynamics","asymptotic vanishing damping","Tikhonov regularization","strong convergence"],"ddc":["510"],"language":[{"iso":"eng"}],"external_id":{"arxiv":["2411.18422"]},"year":"2025","title":"Inertial dynamics with vanishing Tikhonov regularization for multobjective optimization","date_created":"2024-11-28T08:58:17Z"},{"publisher":"Society for Industrial and Applied Mathematics","date_updated":"2024-07-02T09:27:39Z","volume":34,"date_created":"2022-07-28T11:53:02Z","author":[{"full_name":"Sonntag, Konstantin","id":"56399","last_name":"Sonntag","orcid":"https://orcid.org/0000-0003-3384-3496","first_name":"Konstantin"},{"first_name":"Sebastian","orcid":"0000-0002-3389-793X","last_name":"Peitz","id":"47427","full_name":"Peitz, Sebastian"}],"title":"Fast Convergence of Inertial Multiobjective Gradient-Like Systems with Asymptotic Vanishing Damping","doi":"10.1137/23M1588512","publication_identifier":{"issn":["1095-7189"]},"publication_status":"published","issue":"3","year":"2024","page":"2259 - 2286","intvolume":"        34","citation":{"ieee":"K.

To the best of our knowledge, this system is the first inertial gradient-like system for multiobjective optimization problems including asymptotic vanishing damping, expanding the ideas previously laid out in [H. 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. In addition, we obtain a convergence rate of order \\(\\mathcal{O}(t^{-2})\\) for the function values measured with a merit function. This approach presents a good basis for the development of fast gradient methods for multiobjective optimization."}],"status":"public"},{"language":[{"iso":"eng"}],"keyword":["Optimization","Evolutionary computation","Approximation algorithms","Benchmark testing","Vectors","Surveys","Pareto optimization","multi-objective optimization","evolutionary computation","multimodal optimization","local solutions"],"user_id":"15504","_id":"56221","status":"public","publication":"IEEE Transactions on Evolutionary Computation","type":"journal_article","doi":"10.1109/TEVC.2024.3458855","title":"Finding ϵ-Locally Optimal Solutions for Multi-Objective Multimodal Optimization","author":[{"first_name":"Angel E.","full_name":"Rodriguez-Fernandez, Angel E.","last_name":"Rodriguez-Fernandez"},{"last_name":"Schäpermeier","full_name":"Schäpermeier, Lennart","first_name":"Lennart"},{"first_name":"Carlos","full_name":"Hernández, Carlos","last_name":"Hernández"},{"first_name":"Pascal","full_name":"Kerschke, Pascal","last_name":"Kerschke"},{"orcid":"0000-0002-9788-8282","last_name":"Trautmann","full_name":"Trautmann, Heike","id":"100740","first_name":"Heike"},{"full_name":"Schütze, Oliver","last_name":"Schütze","first_name":"Oliver"}],"date_created":"2024-09-24T08:01:14Z","date_updated":"2024-09-24T08:01:47Z","page":"1-1","citation":{"short":"A.E.
