An interactive surrogate-based method for computationally expensive multiobjective optimisation
Tabatabaei, Mohammad; Hartikainen, Markus; Sindhya, Karthik; Hakanen, Jussi; Miettinen, Kaisa (Palgrave Macmillan Ltd., 2019)Many disciplines involve computationally expensive multiobjective optimisation problems. Surrogate-based methods are commonly used in the literature to alleviate the computational cost. In this paper, we develop an interactive ... -
A survey on handling computationally expensive multiobjective optimization problems with evolutionary algorithms
Chugh, Tinkle; Sindhya, Karthik; Hakanen, Jussi; Miettinen, Kaisa (Springer, 2019)Evolutionary algorithms are widely used for solving multiobjective optimization problems but are often criticized because of a large number of function evaluations needed. Approximations, especially function approximations, ... -
Interactive multiobjective optimization of an extremely computationally expensive pump design problem
Burkotová, Jana; Aghaei Pour, Pouya; Krátký, Tomáš; Miettinen, Kaisa (Taylor & Francis, 2023)The hydraulic design of a pump is a challenging optimization problem. It has multiple conflicting objective functions based on computationally very expensive (16–20 hours) numerical simulations, and simulation failures, ... -

On approaches for solving computationally expensive multiobjective optimization problems
Tabatabaei, Seyed Mohammad Mehdi (University of Jyväskylä, 2016)In this thesis, we consider solving computationally expensive multiobjective optimization problems that take into account the preferences of a decision maker (DM). The aim is to support the DM in identifying the most ...
