However, design optimization of TPMS architecture remains a huge challenge due to the convoluted multi parameter-property relationship. In this study, optimization of TPMS structure for composite titania ceramic is accelerated by using the multi-objective optimization algorithm guided finite element method ...

Bayesian optimization has emerged as an efficient approach to optimizing expensive functions, but it has not been, to the best of our knowledge, applied to constrained multi-objective optimization of structural concrete design problems. In this work, we develop a Bayesian optimization framework ...

Current multi-objective BO algorithms cannot deal with mixed variable problems. We present MixMOBO, the first mixed variable, multi-objective Bayesian optimization framework for such problems. Using MixMOBO, optimal Pareto-fronts for multi-objective, mixed variable design spaces can be found efficiently...

We adopted a Bayesian optimization framework where a probabilistic emulator function is constructed to make predictions over the loss functions for each objective from the input space, with a minimum amount of evaluations of the (computationally expensive) simulator. ...
The Expected Hypervolume Improvement (EHVI) is a frequently used infill criterion in Multi-Objective Bayesian Global Optimization (MOBGO), due to its good ability to lead the exploration. Recently, the computational complexity of EHVI calculation is reduced to O(n log n) for both 2-D and 3...
