OptScientist: Automated Discovery of Optimization Laws

精选理由

MIT 式的自动科学发现新玩法:不从数据里拟合公式,而是反推数据背后的优化问题,99 道物理题对了八成,还省 token。

OptScientist 是一个自动科学发现框架,核心是把数据表示为优化问题再提取其符号形式,并用 LLM 智能体系统结合文献先验迭代发现候选定律。团队构建了含 99 个物理优化问题的 OptFeynman 基准,OptScientist 在其中超过 80% 的问题上恢复了真实定律,且对噪声上下文保持稳健,显著优于机器学习、符号回归和 LLM 基线。在人类风险决策和央行货币政策两个真实场景中,发现的符号定律在 held-out 预测上与主流基线相当,但参数更少、token 消耗也大幅降低。

OptScientist: Automated Discovery of Optimization Laws

Many scientific phenomena are best understood as outcomes of underlying optimization problems, yet automated scientific discovery has largely focused on recovering equations that describe observed input-output patterns. We introduce OptScientist, a novel automated framework for discovering compact symbolic optimization laws directly from data. OptScientist comprises (i) a model that infers symbolic optimization problems by first learning to represent data as an optimization problem and then extracting its symbolic form, and (ii) an LLM agentic system embedding the model in a discovery process that integrates theoretical priors from scientific literature, discovers candidate laws, abstracts their underlying mechanisms, and suggests new data to collect. We first evaluate OptScientist on OptFeynman, a novel benchmark of 99 physics-derived optimization problems, where OptScientist recovers ground-truth laws for over 80% of the problems and remains robust to noisy contextual information, while substantially outperforming machine-learning, symbolic, and LLM-based model-discovery baselines. On human risky choice and central-bank monetary policy, OptScientist discovers compact symbolic optimization laws that achieve held-out predictive performance competitive with leading baselines, while using few parameters and substantially fewer tokens than LLM baselines. Overall, OptScientist extends automated scientific discovery to uncovering optimization laws that generate observed phenomena, enabling automated theory building across the physical, biological, behavioral, and social sciences.
