When Efficiency Becomes a Vulnerability: Computational Cost Attacks on WebAgents (2026.acl-long)
Copied to clipboard
| Challenge: | Existing WebAgents suffer from computational cost attacks due to long reasoning processes and excessive computational cost. |
| Approach: | They propose a framework that generates adversarial prompts and a reinforcement learning-enhanced selector to identify the most effective perturbations. |
| Outcome: | The proposed framework exploits large language models to generate diverse adversarial prompts and a reinforcement learning–enhanced selector to identify the most effective perturbations. |
LARA: LLM-based Agile Power Distribution Network Restoration from Disastrous Events (2026.findings-eacl)
Copied to clipboard
| Challenge: | a large language model generates high-level restoration plans over a compact catalogue of feasible actions. |
| Approach: | They propose a method that generates restoration plans over a catalogue of feasible actions. |
| Outcome: | The proposed model outperforms a time-capped solver on an IEEE 13-node power distribution feeder by 13% while using less than 1% of its wall-clock runtime. |
