AutoPDE: Reliable Agentic PDE Solving via Explicitly Represented Solver Strategies

AutoPDE introduces a novel agentic approach to solving partial differential equations by maintaining solver strategies as explicit, inspectable objects rather than implicit code details. The system achieves a 54.5% pass rate on PDE Agent Bench, improving upon existing baselines by 14.2 percentage points through a three-stage process combining PDE analysis, numerical method selection, and adaptive tuning.

Learning Where to Simulate: Generative Active Sampling for Online PDE Surrogate Training

Researchers introduce Online Generative Active Sampling (OGAS), an active learning method that improves PDE surrogate models by strategically sampling challenging configurations during training. Using a parallel diffusion model to steer data generation toward difficult regimes, OGAS reduces worst-case prediction errors across multiple PDE types without significant computational overhead.

CATO: Charted Attention for Neural PDE Operators

Researchers introduce CATO (Charted Axial Transformer Operator), a neural operator architecture that solves partial differential equations (PDEs) on complex geometries more efficiently than existing methods. By learning geometry-adaptive coordinate transformations and incorporating derivative-aware physics supervision, CATO achieves 26.76% performance improvement over competing approaches while reducing parameters by 82%.

PDEAgent-Bench: A Multi-Metric, Multi-Library Benchmark for PDE Solver Generation

Researchers introduced PDEAgent-Bench, the first comprehensive benchmark for evaluating AI systems that generate numerical solvers from partial differential equations (PDEs). The benchmark contains 645 test cases across multiple PDE families and finite-element libraries, revealing that while current LLMs can produce runnable code, they substantially fail when accuracy and efficiency requirements are enforced.
