An Element-wise RSAV Algorithm for Unconstrained Optimization Problems

no code implementations7 Sep 2023 Shiheng Zhang, Jiahao Zhang, Jie Shen, Guang Lin

We present a novel optimization algorithm, element-wise relaxed scalar auxiliary variable (E-RSAV), that satisfies an unconditional energy dissipation law and exhibits improved alignment between the modified and the original energy.

Energy-Dissipative Evolutionary Deep Operator Neural Networks
