For SAT problems with 10 variables and 200 clauses, sometimes outputted UNSAT because it couldn't find any satisfying assignment, and it would take a lot more time to find one, which is logically sound. I don't consider this as bad reasoning as it is about performance. So I tried it with only 100 clauses and it successfully found valid assignments.
2026年中央一号文件提出“发展‘小而美’文旅业态”，明确了乡村游的发展方向。曾经，受困于同质化，乡村游千村一面。究其原因，是重投入、轻运营，重模仿、轻创新，一味追求“大而全”。这不仅忽视了乡村独特价值，还造成资源浪费。相反，“小而美”追求的是轻量化、精品化、特色化，以小投入撬动高效益，这符合产业发展规律，契合文旅消费趋势，贴合乡村实际情况，能有力推动乡村游长远发展。
