The algorithm combines a surrogate-assisted derivative-free trust-region approach with the filter method known from single-objective optimization. Instead of the true objective and constraint functions, so-called fully linear models are employed and we show how to deal with the gradient inexactness in the composite step setting, adapted from single-objective optimization as well. Under standard assumptions, we prove convergence of a subset of iterates to a quasi-stationary point and if constraint qualifications hold, then the limit point is also a KKT-point of the multi-objective problem.","lang":"eng"}],"language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://arxiv.org/pdf/2208.12094"}],"publication":"arXiv:2208.12094","_id":"33150","oa":"1","external_id":{"arxiv":["2208.12094"]},"date_updated":"2022-08-26T06:12:10Z","year":"2022","title":"Multi-Objective Trust-Region Filter Method for Nonlinear Constraints using Inexact Gradients","type":"preprint"}
