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:

其次是聚丙烯（PP），或推动纺织与汽车材料的隐性涨价。伊朗在全球乙烯产能中占比约8%–10%，在聚乙烯尤其是部分高压、低压料上拥有不可忽视的权重；中国自伊朗进口PE约占PE总进口量的9%，这部分货源一旦被阻断，会迫使亚洲买家以更高成本从美国、非洲或其他中东国家接盘。。关于这个话题，快连下载安装提供了深入分析
