Scheduling Your LLM Reinforcement Learning with Reasoning Trees
Unlock Advanced LLM Performance: Precision Scheduling for Complex Reasoning Tasks
This paper introduces Re-Schedule, an innovative data scheduling algorithm for LLM Reinforcement Learning with Verifiable Rewards (RLVR). It leverages a novel 'Reasoning Score' (r-score) that quantifies a query's learning difficulty by analyzing the structural complexity of its reasoning tree, moving beyond traditional path-based accuracy metrics. Re-Schedule builds a dynamic curriculum, starting with structurally simple queries and progressing to more complex ones, leading to significant accuracy improvements in math-reasoning tasks.
Key Enterprise Impact
Re-Schedule provides a robust framework for optimizing LLM training, leading to measurable gains in accuracy and efficiency, critical for complex AI applications.

The core innovation lies in moving beyond simple accuracy to understand the intrinsic learning difficulty of LLM queries through their reasoning tree structure.
r-score
New Metric for Learning Difficulty
Quantifies a query's learning potential based on reasoning tree structure, not just solution accuracy. A higher r-score signifies a more tractable reasoning structure and greater learning efficiency.
| Feature | Reasoning Score (r-score) | Path-Based Metrics (e.g., Accuracy) |
|---|---|---|
| Difficulty Basis | Reasoning Tree Structure, edit budget | Final solution accuracy, path correctness |
| Learning Efficiency | Directly quantifies potential accuracy gain under limited edits (learning potential) | Infers difficulty from success/failure, can be misleading (e.g., easy problem with low initial accuracy appears hard) |
| Scheduling Logic | Curriculum from structurally simple to complex | Curriculum from easy to hard based on current accuracy |
| Focus | Structural relationships & learnability | Outcome-based performance |
| Benefit | More effective identification of truly easy/hard queries, better training efficiency | Simpler to calculate, but can lead to less efficient training if structural complexity is high |

RLVR Training Update
The methodology details how reasoning trees are approximated and how the r-score is rigorously calculated to reflect true learning potential.
k=4, d=4
Optimal Tree Parameters
Approximated reasoning tree uses branching factor k=4 and maximum depth d=4 for best performance without excessive computational overhead.
Node Editing Budget & R-Score
Simulating Learning Potential
The r-score is defined as the maximum potential accuracy gain achievable within a limited 'node editing budget'. This means identifying the most impactful single child branch to prune (Equation 7) and then maximizing the sum of r-scores from a set of M non-conflicting nodes (Equation 8). This effectively simulates the most efficient path to improving a query's accuracy, reflecting its true learnability.
Highlights:
- Limited budget
- Maximum accuracy gain
- Non-conflicting nodes
Empirical results demonstrate Re-Schedule's superior performance across various benchmarks, validating the effectiveness of the r-score metric.

Training as Reasoning Tree Optimization
MCN Metric Validation
Experiments using the Minimum Corrective Nodes (MCN) metric showed a consistent downward trend during training. This indicates that the RL process effectively refines the model's policy at critical decision nodes, directly optimizing the reasoning tree structure as hypothesized.
Highlights:
- MCN decreases
- Policy refinement
- Tree optimization
