用的还是已经被淘汰的老方法。 不得不说，buff有点多（doge）。 这位"门外汉" Boaz Klartag 破解的问题是 高维空间球体堆积 ，顾名思义，是探究如何在给定的高维空间中尽可能多地填充球体。 给定一个d维空间，用Klartag的方法进行堆积，数量可扩大至先前纪录的d倍。 闻乐 发自 凹非寺 量子位 | 公众号 QbitAI 一位"门外汉"闲来无事学了几个月的新理论，居然找到了百年难题的最优解。 也就是说，在 100维 空间中，可以堆积球体的数量大约为先前数量的 100倍 ；在百万维空间中，可以堆积大约100万倍的球体。 这是自罗杰斯在1947年发表论文以来，在球体堆积效率方面最具实质性的改进。 而且他使用的方法，还是早就被主流数学家们抛弃的罗杰斯的"椭球体起始"方法。 其研究结果对于实际应用领域也有重要意义，能为 无线通信 领域效果提升带来新思路。 数十年的微小进展 早在17世纪初，物理学家开普勒就提出，通过像杂货店堆放橙子那样堆叠三维球体，可以填充大约74%的空间，并猜测这是最佳排列方式。 然而，这一猜想的证明却耗费了数学家们将近 400年 时间。 对于空间球体堆积这一问题，数学家 赫尔曼·闵 ...
