A set-based perspective is taken where convergence is measured by performance indicators. The proposed techniques fulfill the requirements of proper statistical assessment on the one hand and efficient optimisation for real-world problems on the other hand. The first approach accounts for the stochastic nature of the MOEA by repeating the optimisation runs for increasing generation numbers and analysing the performance indicators using statistical tools. This technique results in a very robust offline procedure. Moreover, an online convergence detection method is introduced as well. This method automatically stops the MOEA when either the variance of the performance indicators falls below a specified threshold or a stagnation of their overall trend is detected. Both methods are analysed and compared for two MOEA and on different classes of benchmark functions. It is shown that the methods successfully operate on all stated problems needing less function evaluations while preserving good approximation quality at the same time.","lang":"eng"}],"date_created":"2023-08-04T16:19:21Z","publication":"Evolutionary Computation","date_updated":"2024-06-10T11:55:57Z","title":"Statistical Methods for Convergence Detection of Multi-Objective Evolutionary Algorithms","department":[{"_id":"34"},{"_id":"819"}]}
