At the Lean FRO, Kim Morrison, a Senior Research Software Engineer, recently ran an experiment that went well beyond our expectations. An AI agent converted zlib, a widely used C compression library embedded in countless systems, to Lean, with minimal human guidance. No special tooling was built. It was Claude, a general-purpose AI, with no special training for theorem proving, out of the box. The workflow had four steps. First, the AI produced a clean, readable Lean implementation of the zlib compression format, including the DEFLATE algorithm at its core. Second, the Lean version passed the library’s existing test suite, confirming behavioral equivalence. Third, key properties were stated and proved, not as tests, but as mathematical theorems. The capstone theorem:

再往上看,大脑算法几乎是一部技术范式的迭代史。早期的仿真迁移技术虽然解决了初期的模型训练成本,但在面对真实物理世界的摩擦、形变与复杂噪声时,会陷入长序列操作的累积误差,导致在现实里"越做越错"。
