The authors optimized versioned agent harnesses for root-cause localization in hardware design verification.
Evolved Agent Harnesses Improve Coverage but Fail to Consolidate Gains
Automated harness optimization helped a fixed language model complete and sometimes solve more hardware-debugging tasks, but no candidate retained all discovered improvements.

Seyoum and Mittur evolved the runtime instructions and controls around a fixed model, testing candidates on 12 proprietary hardware design-verification debugging tasks with five trials per task.

From NVIDIA
In one line
Automatically evolved LLM agent harnesses improve completion and task coverage in hardware verification, but complementary gains do not reliably consolidate into one consistently superior harness.
