SeaEvo: Advancing Algorithm Discovery with Strategy Space Evolution
SeaEvo introduces a strategy-space layer that treats natural-language algorithm descriptions as first-class evolutionary population members, rather than ephemeral prompt context. This addresses a fundamental limitation in LLM-guided algorithm discovery: current systems conflate syntactically distinct implementations, fail to preserve strategically viable but lower-fitness directions, and cannot detect when entire strategy families have exhausted their potential. By elevating strategic reasoning to the population level, the work enables more efficient search through algorithm space and clearer tracking of which conceptual approaches remain unexplored. The shift matters for automated ML and neural architecture search, where distinguishing strategic intent from implementation details could accelerate discovery cycles.

ExplainerThe core contribution is less about search efficiency per se and more about a representational claim: that natural-language strategy descriptions carry information that code alone cannot, and that losing this layer during evolution is a structural flaw, not just an optimization gap. Most prior LLM-guided search work treats language as a means to generate code, not as a persistent object worth evolving independently.
This connects to a pattern visible across several recent papers in the archive. The 'Kwai Summary Attention' report from the same week illustrates how architectural choices made at the search or design stage compound into costly inefficiencies at scale, which is exactly the problem SeaEvo targets upstream. More broadly, the depression-symptom detection paper ('Learning Evidence of Depression Symptoms via Prompt Induction') surfaced a related tension: standard prompting workflows lose structured intent between iterations, and prompt induction was proposed as a fix. SeaEvo is essentially making the same argument at the algorithm-discovery level, treating strategic intent as something that must be explicitly preserved rather than reconstructed each generation.
The meaningful test is whether SeaEvo's strategy-space representation produces meaningfully different final algorithms on established AutoML benchmarks (such as HPOBench or NAS-Bench-201) compared to code-only evolutionary baselines. If published ablations show strategy-layer removal closing most of the performance gap, the representational argument weakens considerably.
