4chan解决了困扰科学家数十年的难题（的一部分）
真正的标题 4chan自闭肥宅们竟恐怖如斯，一切都在团长预料之中
团长永不过气
Apparently part of the solution to a difficult mathematics problem has been available for years on a 4chan board about anime. The anonymous author provided it as a tip about how to best watch a non-linear series.
在一个数学难题的解决方法求解帖挂在4chan动漫版块数年之后，一位匿名作者提供了如何最优观测非线性数列的窍门。
The amusing story where anime and science intersected was brought to light by Robin Houston, a computer scientist and mathematician on Twitter.
这个故事的有趣之处在于将原本割裂的动漫与科学合一爆发出璀璨光芒，提出者是Robin Houston，一位计算机科学家与数学家。
The problem in question comes from the math field of combinatorics and deals with permutations. A permutation is an act of changing the arrangement, especially the linear order, of a set of items. For instance, the numbers 1, 2 and 3 can be arranged in six different ways, i.e. there are six possible permutations for three elements. A superpermutation is a string that contains all possible permutations of a set as sub-strings.
我不希望在毕业后还看到数学问题，所以此段略过。
In more practical terms, say there is a series of several episodes labeled not chronologically, but absolutely arbitrary. And the series is so bad that you have no way of determining the correct order from the content. If you are determined to watch them the right way at least once, you can start a marathon, playing the episodes again and again until all possible order variants are complete.
说人话的话，就是一个系列剧集不是靠时间顺序排列，而是完全随机的，而糟糕的是也没办法靠内容确定真正的顺序。如果你真的想来上一遍以确定正确顺序，你就要来场马拉松了，把它们看上一遍又一遍直到看完所有可能性。
The example may seem hypothetical, but it was not for fans of an anime called “The Melancholy of Haruhi Suzumiya”, the first season of which contains 14 episodes. It was broadcast in a non-chronological order – as an acknowledgment of its theme of time travel – so fans of the anime have a fad of rearranging and rewatching it again and again.
这似乎就是一个假设，但对于《凉宫春日的忧郁》粉丝们来说可并非如此，因为它的第一季有14集，而且众所周知由于以时间旅行为主题，粉丝们也乐于改变顺序不断重新观看。
So in September 2011 somebody asked on 4chan how long it may take if one were to watch Haruhi in every possible order. And another anonymous poster offered a solution – thus solving the problem of the lower bond for the minimal length of a superpermutation. Jay Pantone, a mathematician at Marquette University, translated the 4chan solution into a formal layout for mathematicians and believes the proof holds up.
所以在2011年9月，有人在4chan上提问如果要看完凉宫所有可能顺序要多长时间，另一位匿名答主给出了解决办法（数学问题一概略过，脑壳痛）
As for the answer to the original Haruhi marathon question, Pantone said one would have to watch no less than 93,884,313,611 episodes and no more than 93,924,230,411 episodes to accomplish the task. Good luck with that.
另外有人给出了这个问题（凉宫集数猜想）的答案，Pantone称一个人要想看完所有可能性那么需要看上不少于93884313611集且不多于93924230411集，祝你好运。

One day 4chan will use their organized autism to find a proof if god exists and how to travel back in time.
总有一天4chan人士将会依靠他们的自闭症患者军团们来证明上帝是否存在和能否进行时间旅行。

I do not understand anything about this math problem. But this is all I have to say: when people work together, great things happen. Do we need a genius? Yes. But collective work is even better.
俺是看不懂这玩意，但俺寻思团结就是力量，相较于天才集体更强大。

Has weaponized autism gone too far?
将自闭症们武器化项目已经进展的恐怖如斯了吗？

Not far enough yet.
还未够班口牙。

Weaponized autism to the rescue.
武器化才是拯救自闭症们的出路。

Forget what they say about the chan boards , 4ch and 8ch, there is a treasure trove of info provided there and some very intelligent discourse.
忘了对4ch和8ch的评论吧，那里还是有埋藏的箴言和智慧的讨论的。

I didn't know this puzzled scientists for decades. Why didn't they ask me?
我不懂为何这会困扰科学家几十年，为毛不问我呢？

It was me, but I don't want publicity. ;)
其实那人是我，只是我不想出名。
IG牛逼！！！
