Goal : Benchmarking Script Refactoring + +## Overall Objective + +Transform the existing benchmarking script into a **maintainable, extensible, and reliable system** to enhance productivity and reliability in research and experimental environments. + +--- + +## Phase-by-Phase Goals + +### Phase 1: Code Structure Improvement + +**Goal**: Transform complex and repetitive code patterns into systematic and manageable structures + +- **Eliminate 80+ line if-elif chain**: Replace optimizer selection logic with centralized configuration system +- **Build dynamic import system**: Implement runtime loading system for required optimizer classes +- **Ensure type safety**: Add type hints throughout codebase for improved IDE support and early error detection +- **Remove code duplication**: Consolidate repetitive import patterns and configuration logic + +### Phase 2: Configuration Management System + +**Goal**: Separate hardcoded values into external configuration to improve experiment flexibility and reproducibility + +- **Create centralized configuration class**: Build system to manage all experiment parameters in one location +- **Support multiple formats**: Support both JSON and YAML configuration files for user convenience +- **Implement template system**: Create template generation functionality for easy configuration startup +- **Progressive enhancement**: Implement new features as opt-in while maintaining existing behavior + +### Phase 3: Reliability & Recovery System + +**Goal**: Ensure experiment execution stability and build recovery capabilities for failure scenarios + +- **Comprehensive error handling**: Implement granular handling logic for various exception scenarios +- **Guarantee experiment continuity**: System to prevent individual experiment failures from terminating entire batch execution +- **Checkpoint and recovery**: State management system for automatic resumption of interrupted experiments +- **Structured logging**: Build detailed logging system for debugging and monitoring + +--- + +## Core Design Principles + +### 1. **Backward Compatibility** +- Complete preservation of existing command-line interface +- Uninterrupted support for existing scripts and workflows +- Maintain identical output format and result storage structure + +### 2. **Progressive Enhancement** +- New features provided as opt-in functionality +- Default behavior remains identical to existing system +- Users can activate advanced features as needed + +### 3. **Extensibility** +- Simple configuration approach for adding new optimizers +- Flexible structure for adding new experiment parameters +- Solid foundation for future feature expansion + +### 4. **Observability** +- Real-time monitoring of experiment progress +- Detailed error information and debugging support +- Performance metrics and experiment statistics tracking + +--- + +## Expected Benefits + +### Developer Perspective +- **60%+ reduction in code maintenance cost**: Simplified change operations through centralized configuration +- **Shortened time to add new optimizers**: Single-line configuration for new optimizer addition +- **Improved debugging efficiency**: Reduced troubleshooting time through structured logging + +### Researcher Perspective +- **Experiment configuration flexibility**: Ability to adjust experiment parameters without code modification +- **Enhanced experiment reproducibility**: Precise experiment environment reconstruction through configuration files +- **Resilience to experiment interruptions**: Automatic experiment resumption through checkpoints + +### System Perspective +- **Improved stability**: Minimized impact of individual experiment failures on entire batch +- **Resource efficiency**: Selective re-execution of only failed experiments +- **Enhanced monitoring**: Real-time progress tracking and performance analysis + +--- + +# Guide + +## Execution Command Examples + +### Step 1: Data Preparation (Run once
