Discovering physical laws with parallel symbolic enumeration
This paper introduces Parallel Symbolic Enumeration (PSE), a novel approach to symbolic regression that addresses long-standing challenges in accuracy, efficiency, and scalability. By leveraging a Parallel Symbolic Regression Network (PSRN) to identify and reuse common subtrees, perform GPU-accelerated parallel evaluation, and integrate with a token generator, PSE significantly outperforms state-of-the-art baselines across diverse benchmarks and real-world problems. It achieves up to 99% higher recovery accuracy and an order of magnitude faster computation, marking a substantial advance in data-driven discovery of interpretable mathematical models and physical laws.

PSRN: The Engine of Discovery
The Parallel Symbolic Regression Network (PSRN) is the cornerstone of PSE, designed for efficient and scalable evaluation of mathematical expressions. It addresses the combinatorial explosion problem by automatically identifying and reusing common subtrees across candidate expressions, thereby avoiding redundant computations. This process, coupled with GPU-based parallel search, allows PSRN to evaluate hundreds of millions of expressions simultaneously in mere seconds. The network layers build progressively complex expressions from a base set of operators and variables, enhancing the depth and intricacy of discoverable models. This shared-computation framework significantly accelerates the search for optimal symbolic representations.
Enhanced Search Strategy with Token Generators
To explore more complex and deeply nested expressions, PSRN is integrated into an iterative loop with a token generator, such as Genetic Programming (GP) or Monte Carlo Tree Search (MCTS). This generative component proposes new sets of promising base expressions (tokens) in each iteration. These tokens, along with sampled constants, are fed back into PSRN for evaluation. A reward signal, balancing accuracy and complexity, guides the token generator to progressively build and refine complex equations, enabling the discovery of structures unreachable by a single pass of PSRN alone. This iterative refinement process is critical for tackling intricate scientific problems.

Real-World Impact: Discovering Physical Laws
Turbulent Friction & Chaotic Dynamics
PSE demonstrates its prowess in discovering underlying physical laws from experimental data. For the electro-mechanical positioning system (EMPS), it successfully uncovers governing equations despite noise and nonlinearity. In the domain of fluid mechanics, PSE accurately distills the turbulent friction law from the Nikuradse dataset, revealing the relationship between Reynolds number, roughness, and friction factor. Furthermore, PSE effectively identifies multi-dimensional autonomous chaotic dynamics, such as the Lorenz attractor, from noisy trajectories, showcasing its robustness and capability in complex real-world scenarios. These applications highlight PSE's potential to accelerate scientific discovery and improve system understanding.
