Papers with multi-constraint tasks
VestaBench: An Embodied Benchmark for Safe Long-Horizon Planning Under Multi-Constraint and Adversarial Settings (2025.emnlp-industry)
Copied to clipboard
| Challenge: | Existing safety benchmarks do not represent a diverse range of multi-constraint tasks that require long-horizon planning with a focus on safety. |
| Approach: | They propose a benchmark to assess the safety of embodied AI agents under multiple constraints. |
| Outcome: | The proposed benchmarks show that LLMs perform poorly against their tasks . they also suffer significantly compromised safety outcomes . |
Instructions are all you need: Self-supervised Reinforcement Learning for Instruction Following (2026.acl-long)
Copied to clipboard
| Challenge: | Existing reinforcement learning approaches suffer from dependency on external supervision and sparse reward signals from multi-constraint tasks. |
| Approach: | They propose a self-supervised reinforcement learning framework that eliminates dependency on external supervision by deriving reward signals directly from instructions and generating pseudo-labels for reward model training. |
| Outcome: | The proposed framework achieves strong improvements across 3 in-domain and 5 out-of-domain datasets while maintaining computational efficiency. |
