Black-hole kicks from numerical-relativity surrogate models [PDF]
, 2018 Binary black holes radiate linear momentum in gravitational waves as they merge. Recoils imparted to the black-hole remnant can reach thousands of km/s, thus ejecting black holes from their host galaxies.

Spatio-Temporal Gradient Enhanced Surrogate Modeling Strategies
Mathematical and Computational Applications, 2023 This research compares the performance of space-time surrogate models (STSMs) and network surrogate models (NSMs). Specifically, when the system response varies over time (or pseudo-time), the surrogates must predict the system response.

Fast prediction and evaluation of gravitational waveforms using surrogate models [PDF]
, 2013 [Abridged] We propose a solution to the problem of quickly and accurately predicting gravitational waveforms within any given physical model. The method is relevant for both real-time applications and in more traditional scenarios where the generation of

Empirical Study of Data-Driven Evolutionary Algorithms in Noisy Environments
Mathematics, 2022 For computationally intensive problems, data-driven evolutionary algorithms (DDEAs) are advantageous for low computational budgets because they build surrogate models based on historical data to approximate the expensive evaluation.

Surrogacy-Based Maximization of Output Power of a Low-Voltage Vibration Energy Harvesting Device
Applied Sciences, 2020 The coreless microgenerators implemented in electromagnetic vibration energy harvesting devices usually suffer from power deficiency. This can be noticeably improved by optimizing the distribution of separate turns within the armature winding.
