ShinkaEvolve: Towards Open-Ended and Sample-Efficient Program Evolution

ICLR 2026poster

We introduce ShinkaEvolve: a new framework leveraging large language models (LLMs) to advance scientific discovery with state-of-the-art performance and efficiency. The field of LLM-driven scientific discovery has seen significant progress, but has yet to overcome a critical limitation: sample ineff…

ALE-Bench: A Benchmark for Long-Horizon Objective-Driven Algorithm Engineering

NeurIPS 2025poster

How well do AI systems perform in algorithm engineering for hard optimization problems in domains such as package-delivery routing, crew scheduling, factory production planning, and power-grid balancing? We introduce $\textit{ALE-Bench}$, a new benchmark for evaluating AI systems on score-based algo…

Wider or Deeper? Scaling LLM Inference-Time Compute with Adaptive Branching Tree Search

NeurIPS 2025spotlight

Recent advances demonstrate that increasing inference-time computation can significantly boost the reasoning capabilities of large language models (LLMs). Although repeated sampling (i.e., generating multiple candidate outputs) is a highly effective strategy, it does not leverage external feedback s…
