亲吻数又叫牛顿数，是希尔伯特第十八问题（球体堆积）的局部形式，和通信技术中的"比特拥挤"问题是同一套底层逻辑。 闻乐 发自 凹非寺 量子位 | 公众号 QbitAI 情人节到了… 那咱也来应应景，讲讲亲吻这件事—— AI的打开方式。 你或许知道，数学上有个正经问题叫做 亲吻数（Kissing Number Problem） ，卡了人类300多年，但就在最近，被 中国AI 狠狠推了一 把。 简单说，它研究的是：在n维空间中，一个球体周围，最多能有多少个和它大小相同的球体，刚好与它相切（kiss），不重叠的那种 。 它源自于1694年，牛顿和格雷戈里两位大佬的争吵： 在三维空间里，一个球周围到底能放12个，还是13个同款球？牛顿坚持12，格雷戈里不服，结果谁也没能当场辩过谁。 直到1953年，数学家用了 258年 时间才严格证明牛顿是对的。 就连2022年获得 菲尔兹奖 的玛丽娜·维亚佐夫斯卡， 正是凭借解决8维和24维空间的最密球体堆积问题，摘得桂冠。 但再往高维走，人类的直觉就崩了。在过去近50年里，亲吻数构造仅有7次实质性进展，而且每一次的方法都完全不同，在临近维度上难以迁 移与复用。 现在，僵局被打破了。 ...
