## Line Graphs: Accuracy vs. Number of Samples (N) for CFLUE and MATH500
### Overview
The image contains two line graphs comparing the accuracy of different models (PASS@N, Fin-PRM, Maj@N, Qwen2.5-MATH-PRM-7B, Qwen2.5-MATH-PRM-72B) across two datasets: **CFLUE** (top graph) and **MATH500** (bottom graph). The x-axis represents the number of samples (N) on a logarithmic scale (2⁰ to 2⁴), and the y-axis represents accuracy in percentage. Each model is represented by a distinct line style and color, as defined in the legend.

### Key Observations
1. **PASS@N** consistently outperforms other models in both datasets, showing the most significant improvement with increased samples.
2. **Maj@N** exhibits a temporary dip at 2¹ in both graphs but recovers by 2⁴.
3. **Qwen2.5-MATH-PRM-72B** (green dashed line) performs best in **MATH500**, surpassing other models at higher sample sizes.
4. **Qwen2.5-MATH-PRM-7B** (blue dashed line) shows mixed performance: a decline in CFLUE but steady growth in MATH500.
5. **Fin-PRM** (black solid line) demonstrates stability in both datasets but lacks the growth seen in PASS@N.

### Interpretation
- **PASS@N** is the most effective model for improving accuracy with more samples, suggesting it is optimized for scalability.
- **Qwen2.5-MATH-PRM-72B** excels in **MATH500**, indicating its architecture is particularly suited for mathematical reasoning tasks.
- The **Maj@N** dip at 2¹ may reflect overfitting or inefficiencies at smaller sample sizes, which are mitigated at larger scales.
- **Qwen2.5-MATH-PRM-7B** underperforms in CFLUE but shows promise in MATH500, highlighting dataset-specific model effectiveness.
- All models improve with more samples, but the rate of improvement varies, emphasizing the importance of model selection based on task requirements.
