spsa

Simultaneous perturbation stochastic approximation implemented in Rust.

• Fast convergence
• Black-box, derivative-free optimization
• Stochastic functions (can be used on noisy functions)
• Converges well in higher-dimensions
• Automatic learning rate tuning and adaptive moment estimation
• Reusable allocation (does not allocate during optimization process)
• SIMD optimization
