We formulate offline tuning of Model Predictive Path Integral (MPPI) controllers as a chance-constrained black-box optimization problem and develop an update-aware framework based on Matrix Adaptation Evolution Strategy (MA-ES). We use statistical information from noisy controller evaluations to determine when the evol...

Four groups of subspace methods for nonlinear monotone equations, with applications to large-scale machine learning problems, using Jacobian-free subspace directions of conjugate-gradient type combined with either fixed step sizes or variable step sizes generated by the projected method of Solodov and Svaiter are intro...

An enhanced local optimization strategy based on curved line search (CLS) is introduced and integrated into AutoDock Vina, resulting in Vina_CLS, demonstrating that improved local optimization can substantially enhance docking performance.

Numerical experiments on nonsmooth test problems with dimensions up to 1000 show that both proposed variants are robust for lower and medium accuracy requirements, while the matrix conjugate-subgradient variant remains the most reliable under the strictest tolerance.
