Papers with dual-agent architecture
CodeEvo: Interaction-Driven Synthesis of Code-centric Data through Hybrid and Iterative Feedback (2026.acl-long)
Copied to clipboard
| Challenge: | Existing methods for generating instruction-code pairs rely on rigid heuristics and are labor-intensive. |
| Approach: | They propose a dual-agent architecture that integrates a Coder and a Reviewer to orchestrate the generation trajectory. |
| Outcome: | The proposed architecture outperforms baselines on a large-scale dataset of instruction-code pairs with stepped difficulty levels. |
Reinforcing Agentic Search Via Reward Density Optimization (2026.acl-long)
Copied to clipboard
| Challenge: | Reinforcement Learning with Verifiable Rewards (RLVR) is a promising approach for enhancing agentic search, but its performance is often hindered by reward sparsity . |
| Approach: | They propose a new research problem to improve the reward obtained per unit of exploration cost by using a system that decomposes long-horizon tasks into intermediate objectives and assigns process-level rewards to provide denser learning signals. |
| Outcome: | The proposed framework outperforms strong baselines on several agentic search benchmarks and achieves comparable performance to that of advanced proprietary models. |
