Simple Extensions of Single-Objective Acquisition Functions and Hedge Strategies for Multi-Objective Bayesian Optimization
Haris Moazam Sheikh
Multi-objective Bayesian optimization (MOBO) is commonly approached through specialized acquisition functions or scalarization schemes designed to explicitly account for trade-offs…
Bayesian optimization and topographic exploration of drag-reducing dimples for aerodynamic surfaces
Sangjoon Lee, M. Erden Yildizdag, Haris M. Sheikh
Dimples offer a promising route to reducing drag on aerodynamic surfaces. However, whether such shallow concavities yield a net benefit depends sensitively on their topography, whi…
MAST: A Multi-fidelity Augmented Surrogate model via Spatial Trust-weighting
Ahmed Mohamed Eisa Nasr, Ali Elham, Haris Moazam Sheikh
In engineering design and scientific computing, computational cost and predictive accuracy are intrinsically coupled. High-fidelity simulations provide accurate predictions but at…
Airfoil optimization using Design-by-Morphing with minimized design-space dimensionality
Sangjoon Lee, Haris Moazam Sheikh
Effective airfoil geometry optimization requires exploring a diverse range of designs using as few design variables as possible. This study introduces AirDbM, a Design-by-Morphing…
Optimized Fish Locomotion using Design-by-Morphing and Bayesian Optimization
Hamayun Farooq, Imran Akhtar, Muhammad Saif Ullah Khalid +1
Nature has always inspired scientists and engineers to understand the underlying mechanism leading to optimal design in bio-inspired dynamics. This study presents a computational f…
Optimization of the Shape of a Hydrokinetic Turbine's Draft Tube and Hub Assembly Using Design-by-Morphing with Bayesian Optimization
Haris Moazam Sheikh, Tess A. Callan, Kealan J. Hennessy +1
Finding the optimal design of a hydrodynamic or aerodynamic surface is often impossible due to the expense of evaluating the cost functions (say, with computational fluid dynamics)…
Airfoil Optimization using Design-by-Morphing
Haris Moazam Sheikh, Sangjoon Lee, Jinge Wang +1
We present Design-by-Morphing (DbM), a novel design methodology applicable to creating a search space for topology optimization of 2D airfoils. Most design techniques impose geomet…
Bayesian Optimization For Multi-Objective Mixed-Variable Problems
Haris Moazam Sheikh, Philip S. Marcus
Optimizing multiple, non-preferential objectives for mixed-variable, expensive black-box problems is important in many areas of engineering and science. The expensive, noisy, black…
