@Orca 如果特朗普真要互联,绝对是一场狂欢!除了左派的屏蔽,更值得一提的是他们可能会遭到混沌邪恶的右派喷子各种骚扰和恶搞——上次 Gab 的管理员被这群人气疯了,在视频里大骂 "Your whole fucking mentality has expired, hahahahaha!!!",成为了联邦宇宙历史上的一大笑话。
* A closed-form solution for the problem describes in this video: https://m.youtube.com/watch?v=bRIL9kMJJSc (maybe not lesser-known? But it doesn't even have its own Wikipedia page!)
Lesser known unsolved mathematical problems I find unreasonably fascinating:
* Is the Leyland-mapping injective?
* We have Kadane's algorithm for the maximum subarray problem, which runs in O(n), is there an algorithm for the maximum submatrix problem which runs in O(n²)? What about higher-dimensional tenors?
* The polyhedral numbers conjecture: is every number the sum of m+1 n-hedral numbers, where m is the number of vertices of the polyhedron. Does it hold for any n-dimensional polytope?
if there is a reachable maximal economic productivity of matterenergy/spacetime, then at some point economic progress will slow from exponential to cubic, since if one expands at a constant fraction of c, then the growth is proportional to the volume of the sphere, which with constantly expanding radius is cubic.
I operate by Crocker's rules[1].
