# Technical Document Extraction: Line Chart Analysis
## Chart Overview
The image is a line chart comparing the accuracy of three different methods across varying computational budgets (number of model generations). The chart includes two reference lines for benchmark models.
## Axes
- **X-axis**: Budget (# of model generations)
- Logarithmic scale from 2⁰ to 2⁷
- Tick labels: 2⁰, 2¹, 2², 2³, 2⁴, 2⁵, 2⁶, 2⁷
- **Y-axis**: Accuracy
- Linear scale from 0.700 to 0.875
- Tick labels: 0.700, 0.725, 0.750, 0.775, 0.800, 0.825, 0.850, 0.875
## Legend
- **Location**: Lower-right quadrant
- **Entries**:
1. **Blue squares**: Ours-Particle Filtering (Qwen2.5-Math-1.5B-Instruct)
2. **Red diamonds**: Weighted BoN (Qwen2.5-Math-1.5B-Instruct)
3. **Purple diamonds**: DVTS (Qwen2.5-Math-1.5B-Instruct)

## Reference Lines
- **o1-preview**: Horizontal dotted line at y=0.875
- **GPT-4o**: Horizontal dotted line at y=0.75
## Additional Labels
- **Qwen2.5-Math-7B-Instruct**: Horizontal dotted line at y=0.80
- **GPT-4o**: Horizontal dotted line at y=0.75
## Spatial Grounding
- **Legend**: Lower-right quadrant (x > 0.5, y < 0.5 in normalized coordinates)
- **Data Point Colors**:
- Blue squares match "Ours-Particle Filtering"
- Red diamonds match "Weighted BoN"
- Purple diamonds match "DVTS"
## Trend Verification
- **Blue Line**: Consistent upward trajectory with minor fluctuations
- **Red Line**: Sharp rise to 2⁴, then slight decline and stabilization
- **Purple Line**: Steady increase until 2⁵, then plateau
