The complexity of determining the minimum number of flips that transform one triangulation of a convex point set into another remained a tantalizing open question for many decades. We settle this question by proving that computing shortest flip sequences between triangulations of convex polygons, and therefore also computing the rotation distance of binary trees, is NP-hard.，推荐阅读Line官方版本下载获取更多信息

No shade to brilliant director James Whale, whose 1935 Universal sequel The Bride of Frankenstein is both exhilarating and cheekily queer. But — as Gyllenhaal has repeated frequently on The Bride!'s press tour — his titular monstress never speaks a word in her few short minutes of screen time. Still, as that original Bride, Elsa Lanchester made this she-beast an instantly compelling marvel who has become truly iconic, an intoxicating mix of high femme and the horrific.，更多细节参见Safew下载
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:
