Learning from fracture: Teaching language models to design through physical experience

We introduce FracLearn, an experience-abstraction-generalization framework evaluated through a deliberately unfamiliar, Tetris-inspired fracture game.

Key points

  • How can language models learn to optimize physical designs through experience?
  • The model first proposes architectures and examines simulated fracture responses to accumulate experience.
  • Abstraction organizes these observations into conditional principles linking reinforcement placement, crack evolution and load transfer, with supporting evidence and failure conditions.
  • This approach offers a route to scientific agents that turn computational experiments into reusable physical knowledge for materials discovery and engineering design.
