Scientific Machine Learning for Coating Degradation and Corrosion Prediction: A Critical Review and Thermodynamic Research Perspective

Coating degradation and corrosion prediction are moving from empirical regression toward scientific machine learning (SciML), which embeds governing equations, geometry, and uncertainty into data-driven models. This critical review examines physics-informed neural networks (PINNs), neural operators, phase-field hybrids...

Adaptive Scoring-and-Memory Policies for Repair Intensification in the Multi-Demand Multidimensional Knapsack Problem: A Comparative Analysis of Solution Quality and Trajectory Diversity

The Multi-Demand Multidimensional Knapsack Problem (MDMKP) combines upper-bound capacities and lower-bound demands, producing a restrictive feasible region. We study three swap-based repair-intensification policies in a common hybrid framework: lightweight Hash tabu search, randomly sampled tabu search, and online lear...
