A Statistical Benchmark of Metaheuristic Algorithms for Nonlinear Soil Constitutive Model Calibration

This study establishes a comprehensive statistical benchmarking framework to evaluate eight metaheuristic algorithms for calibrating three nonlinear soil constitutive models, revealing that algorithm performance varies significantly with model complexity and that low objective-function values do not guarantee accurate parameter recovery due to equifinality.

Full-Field State Estimation from Sparse Point Sensors via Adaptive  Data-Driven Modeling and Sequential Data Assimilation for Nonlinear Dynamical Systems

This paper proposes a fully data-driven framework that combines compressed sensing, adaptive Dynamic Mode Decomposition with control (DMDc) calibrated via DCC-GARCH, and reduced-order Kalman filtering to accurately reconstruct full-field states of nonlinear dynamical systems from sparse and noisy point-sensor measurements without relying on first-principles models.
