Fortified Test Functions for Global Optimization and the Power of Multiple Runs
Charles F. Jekel, Raphael T. Haftka
Some popular functions used to test global optimization algorithms have multiple local optima, all with the same value. That is all local optima are also global optima. This paper…
Multilevel Monte Carlo Simulations of Composite Structures with Uncertain Manufacturing Defects
T. J. Dodwell, S. Kinston, R. Butler +3
By adopting a Multilevel Monte Carlo (MLMC) framework, we show that only a handful of costly fine scale computations are needed to accurately estimate statistics of the failure of…
Safety-margin-based design and redesign considering mixed epistemic model uncertainty and aleatory parameter uncertainty
Nathaniel B. Price, Mathieu Balesdent, Sébastien Defoort +3
At the initial design stage engineers often rely on low-fidelity models that have high epistemic uncertainty. Traditional safety-margin-based deterministic design resorts to testin…
