AI-DRIVEN SCIENTIFIC DISCOVERY
Science-Gym: A Simple Testbed for AI-Driven Scientific Discovery
Automating scientific discovery, particularly equation discovery (symbolic regression), has been a long-standing goal in AI. While recent AI successes in protein folding and material optimization are impactful, they often don't deepen scientific understanding. This paper introduces Science-Gym, a novel Python testbed designed to advance AI-driven scientific discovery by requiring agents to autonomously perform data collection, experimental design, and discover the underlying equations of phenomena. Compatible with Gym, it features seven scientific simulations covering basic physics and epidemiology, allowing evaluation of agents not just on task performance, but crucially, on their ability to uncover interpretable mathematical descriptions of dynamic systems.
Executive Impact: Revolutionizing Scientific Inquiry
Science-Gym offers enterprises a robust framework to develop AI agents capable of accelerating scientific research and discovery, fostering innovation across R&D, and enabling new breakthroughs through autonomous experimentation and interpretable model generation.

The Vision: Autonomous Scientific Discovery
Science-Gym addresses a fundamental gap in AI for science: the ability for agents to autonomously conduct the full scientific process—from experimental design and data collection to the discovery of human-understandable mathematical equations. Unlike black-box predictive models, Science-Gym champions interpretable AI, aiming to provide clear insights into underlying phenomena and foster scientific understanding.
Emulating the Scientific Loop
Science-Gym integrates Reinforcement Learning (RL) for dynamic experimental design and data collection with Symbolic Regression (SR) for discovering governing equations. This cyclical approach mirrors the iterative nature of human scientific inquiry.

A Suite of Seven Scientific Environments
The testbed features seven diverse simulations, carefully chosen to represent core principles in physics and epidemiology. These include classic mechanics problems such as the Law of the Lever, Projectile Motion, the Inclined Plane, and Brachistochrones, as well as complex systems like Lagrangian Points in Space, the epidemiological SIRV Model, and a real-world challenge: the Friction Force of a Droplet. Each environment offers unique challenges for data collection and equation discovery.
These environments are designed to evaluate agents on both task performance and their ability to uncover the underlying mathematical descriptions, pushing the boundaries of AI in scientific research.
Graduated Autonomy: From Full Support to Open Challenge
Science-Gym introduces a framework for evaluating agents across varying levels of autonomy, defined by the type of observations (tabular vs. raw pixels) and nature of rewards (explicit, noisy, or none). The contexts include:
- Full Support: Explicit rewards, tabular data (e.g., used by the "Threshold-and-Save" baseline).
- Partial Support: Noisy rewards, raw observational data.
- Minimal Support: No explicit rewards, raw data.
- Full Autonomy: Self-generated rewards, inferring results from indirect/incomplete data.
While baselines show success with 'full support', the true challenge lies in scenarios with noisy or sparse rewards, and ultimately, no rewards at all, where agents must intrinsically discover interesting experimental states. This spectrum allows for focused research into different components of autonomous discovery.
Science-Gym vs. BoxingGym: A New Paradigm
Science-Gym distinguishes itself from other testbeds like BoxingGym by focusing on deterministic equations, utilizing open-source RL algorithms, and prioritizing quantitative equation outputs. This contrasts with BoxingGym's reliance on commercial LLMs, probabilistic systems, and natural language explanations.
| Characteristic | BoxingGym | Science-Gym |
|---|---|---|
| Type of scientific problem | Probabilistic equations | Deterministic equations |
| Input into experiments | Arrays with parameters | Arrays with parameters |
| Focus of the project | Prompt generation, and LLM answer parsing | Selecting experiments, and equation discovery |
| Dependencies | Commercial LLMs (OpenAI or Claude) | Open source RL algorithms |
| Agents | LLMs | RL algorithms |
| Explanation | Natural language and programs (pymc) | Table of interesting measurements and equations |
| Metric | New agent prediction after explanation | Error on test data |
Science-Gym also enables significantly higher experiment throughput at a lower cost, making it an efficient platform for developing and benchmarking truly autonomous scientific discovery agents without heavy reliance on external APIs or pre-trained multi-task models.
