//! ## Optimizers
//!
//! ### Adam and AdamW
//!
//! Adaptive Moment Estimation with optional weight decay:
//! ```rust,no_run
//! use trustformers_optim::{AdamW, OptimizerState};
//! use trustformers_core::traits::Optimizer;
//!
//! let mut optimizer = AdamW::new(
//!     1e-3,           // learning_rate
//!     (0.9, 0.999),   // (beta1, beta2)
//!     1e-8,           // epsilon
//!     0.01,           // weight_decay
//! );
//!
//! // Ready to use in training loop with .zero_grad(), .update(), and .step()
//! ```
//!
//! ### SGD
//!
//! Stochastic Gradient Descent with momentum and Nesterov acceleration:
//! ```rust,no_run
//! use trustformers_optim::SGD;
//!
//! let optimizer = SGD::new(
//!     0.1,        // learning_rate
//!     0.9,        // momentum
//!     1e-4,       // weight_decay
//!     true,       // nesterov
//! );
//! ```
//!
//! ### Schedule-Free Optimizers
//!
//! Revolutionary optimizers that eliminate the need for learning rate scheduling:
//! ```rust,no_run
//! use trustformers_optim::{ScheduleFreeAdam, ScheduleFreeSGD};
//! use trustformers_core::traits::Optimizer;
//!
//! // Schedule-Free Adam - no learning rate scheduling needed!
//! let optimizer = ScheduleFreeAdam::for_language_models();
//!
//! // Higher learning rates work better (e.g., 0.25-1.0 instead of 0.001)
//! let optimizer = ScheduleFreeAdam::new(0.5, 0.9, 0.95, 1e-8, 0.1);
//!
//! // Schedule-Free SGD for simpler models
//! let optimizer = ScheduleFreeSGD::for_large_models();
//!
//! // No learning rate scheduler needed! Just use .zero_grad(), .update(), .step()
//! // eval_mode() can be used to switch to average weights
//! ```
//!
//! ### Cutting-Edge 2024-2025 Optimizers
//!
//! The latest state-of-the-art optimizers for superior performance:
//!
//! #### 🌟 **NEW: Latest 2025 Research Algorithms** 🚀
//!

//! // 4-bit Adam with NF4 quantization (75% memory savings)
//! let optimizer = Adam4bit::new(0.001, 0.9, 0.999, 1e-8, 0.01);
//!
//! // Custom quantization configuration
//! let quant_config = AdvancedQuantizationConfig {
//!     method: QuantizationMethod::NF4,
//!     block_size: 64,
//!     adaptation_rate: 0.01,
//!     double_quantization: true,
//!     ..Default::default()
//! };
//!
//! let optimizer = Adam4bit::with_quantization_config(
//!     Default::default(),
//!     quant_config,
//! );
//!
//! // Massive memory savings for large models
//! println!("Memory savings: {:.1}%", optimizer.memory_savings() * 100.0);
//! ```
//!
//! ## Learning Rate Schedules
//!
//! Control learning rate during training:
//! ```rust,no_run
//! use trustformers_optim::{AdamW, CosineScheduler, LRScheduler};
//!
//! let base_lr = 1e-3;
//! let optimizer = AdamW::new(base_lr, (0.9, 0.999), 1e-8, 0.01);
//!
//! // Cosine annealing with warmup
//! let scheduler = CosineScheduler::new(
//!     base_lr,
//!     1000,   // num_warmup_steps
//!     10000,  // num_training_steps
//!     1e-5,   // min_lr
//! );
//!
//! // Update learning rate each step
//! for step in 0..10000 {
//!     let current_lr = scheduler.get_lr(step);
//!     // Use current_lr with optimizer.set_lr(current_lr)
//! }
//! ```
//!
//! ## ZeRO Optimization
//!
//! Memory-efficient distributed training:
//! ```rust,ignore
//! // ZeRO distributed training (requires distributed environment)
//! use trustformers_optim::{AdamW};
//!
//! let optimizer = AdamW::new(1e-4, (0.9, 0.999), 1e-8, 0.01);
//! // ZeRO configuration and distributed setup would go here
//! ```
//!
//! ### ZeRO Stages
//!
//! - **Stage 1**: Optimizer state partitioning (4x memory reduction)
//! - **Stage 2**: Optimizer + gradient partitioning (8x memory reduction)
//! - **Stage 3**: Full parameter partitioning (Nx memory reduction)
//!
//! ## Multi-Node Training
//!
//! Scale training across multiple machines:
//! ```rust,ignore
//! // Multi-node distributed training setup
//! // Configuration and training would require distributed environment
//! // Example: MultiNodeTrainer::new(config)
//! ```
//!
//! ## Advanced Features
//!
//! ### Gradient Accumulation
//! ```rust,ignore
//! // Example: Accumulate gradients over multiple batches before stepping
//! // if (step + 1) % accumulation_steps == 0 {
//! //     optimizer.step(&mut model.parameters())?;
//! //     optimizer.zero_grad();
//! // }
//! ```
//!
//! ### Mixed Precision Training
//! ```rust,ignore
//! // Mixed precision optimizers can provide memory savings and speed improvements
//! // Configuration example:
//! // MixedPrecisionOptimizer::new(base_optimizer, scale_config)
//! ```
//!
//! ## Performance Tips
//!
//! 1. **Choose the Right Optimizer**:
//!    - AdamW for most transformer training
//!    - SGD for fine-tuning with small learning rates
//!    - LAMB for large batch training
//!
//! 2. **Learning Rate Scheduling**:
//!    - Use warmup for stable training start
//!    - Cosine schedule for most cases
//!    - Linear decay for fine-tuning
//!
//! 3. **Memory Optimization**:
//!    - Enable ZeRO Stage 2 for models > 1B parameters
//!    - Use gradient accumulation for larger effective batch sizes
//!    - Consider CPU offloading for very large models
//!
//! 4. **Distributed Training**:
//!    - Use data parallelism for models < 10B parameters
//!    - Add model parallelism for larger models
//!    - Enable communication overlap for better throughput

// Allow common patterns in optimizer implementations
