Can you solve the multiverse rescue mission riddle

你能解決多元宇宙救援任務(wù)之謎嗎

來源視頻

It was a normal Tuesday at the superconductor, until a bug in the system created a small situation.?Now your team is trapped in eleven separate pocket dimensions.?

Luckily for you, there’s a half-finished experimental teleportation robot that may be able to get you all home, if you can figure out how to work through the quirks of its design.?

Over interdimensional radio, your engineers explain that the robot can teleport into the alternate universes you’re trapped in, but it’ll do so completely at random.

這是超導(dǎo)體實(shí)驗(yàn)室的一個(gè)普通星期二，但一個(gè)系統(tǒng)漏洞造成一個(gè)突發(fā)小狀況，把你的團(tuán)隊(duì)困在?11?個(gè) 單獨(dú)的空間維度里。

幸運(yùn)的是，有一個(gè)實(shí)驗(yàn)性 遠(yuǎn)距傳送機(jī)器人半成品，若能弄懂其古怪設(shè)計(jì)和如何操控，它可能會(huì)把你們送回家。

你的工程師通過跨維無(wú)線電解釋說，機(jī)器人可以隨機(jī)穿越到你們被困的另一個(gè)宇宙。

The robot has two levers and one big button.?

When it appears, you just switch the position of one of the levers from A to B or vice versa, and then the robot will note your dimensional position and teleport to another of the eleven dimensions at random.

If it shows up again, you’ll have to pull a lever before it’ll teleport away.?

When anyone presses the button, the robot will bring everyone who pulled a lever back home.?

Anyone who didn’t will be lost in the multi-verse forever.

機(jī)器人有兩個(gè)控制桿和一個(gè)大按鈕，

當(dāng)它出現(xiàn)時(shí)，你只需切換任意一個(gè)控制桿的位置， 從?A?到?B，或從?B?到?A，機(jī)器人就會(huì)記住你所在的維度位置，并隨機(jī)穿越到?11?個(gè)空間維度中的一個(gè)。

若它再次出現(xiàn)，你必須 變換控制桿的位置，它才會(huì)離開。當(dāng)有人按下按鈕時(shí)，機(jī)器人會(huì)把曾拉動(dòng)控制桿的人全帶回家。

而沒有拉過控制桿的人， 將會(huì)永遠(yuǎn)迷失在多元宇宙中。

The challenge is to make sure everyone has pulled a lever before anyone hits the button.

While you can talk to each other now over the interdimensional radio and agree on a plan, the robot’s teleportation technology will interfere with all attempts at communication once it arrives.?

You won’t be able to attach messages to the robot or scratch notes into its superstrong alloy body.?

Your only way to communicate information is to change the position of exactly one lever or hit the button.?

What plan will make sure everyone gets home??

Pause the video now if you want to figure it out for yourself.?

挑戰(zhàn)在于，如何在按下按鈕前，確保每個(gè)人都拉了控制桿。

雖然你現(xiàn)在可以用跨維無(wú)線電互相交談，并一起制定方案，但機(jī)器人一旦抵達(dá)，其遠(yuǎn)程傳送技術(shù)會(huì)干擾所有的通信。

你無(wú)法在機(jī)器人身上附加消息，也不能在其超強(qiáng)的合金體上刻字。

你們溝通的唯一方式，就是改變一個(gè)控制桿的位置或按下按鈕。

什么樣的計(jì)劃將確保每人都能回家呢？

It would be nice if you could set different combinations of the levers to indicate who’s already been visited by the robot.?But it has only two levers.?

That gives four combinations— far too few to communicate about 11 people, especially when you’re forced to flip one to send the robot onward.

There must be another way.?

The critical insight is that not everyone has to know when every pocket dimension has been visited.

If one person accepts responsibility ahead of time for hitting the button, then only they need to know who the robot has visited.

In fact, they don’t even need to know exactly who’s been visited… just how many people have been.

用控制桿的位置組合 來代表機(jī)器人訪問過誰(shuí)，是個(gè)不錯(cuò)的主意，但它只有兩個(gè)控制桿，

即僅有四種組合——組合太少了，無(wú)法代表?11?人，特別是你必須用掉一個(gè)組合， 才能讓機(jī)器人去其他人那里。

肯定有另外一種方式。

解題關(guān)鍵在于，并非每個(gè)人都必須了解 哪些空間維度已被訪問過。

如果某人提前接受按下按鈕的任務(wù)，那么，只需他知道機(jī)器人訪問過誰(shuí)即可。

其實(shí)，他甚至無(wú)須知道 機(jī)器人去過誰(shuí)那里……只需知道去過多少人那里即可。

You volunteer to be the person in charge of pressing the button when the moment is right, and give the following directions to everyone else.?

Your plan is simple: you’ll use the left lever to count visits, and the right lever will have no meaning, so there’s no harm in moving it up or down.?

Each of the others will pull the left lever from position A to position B exactly once.

If the robot appears with the left lever already pulled down, or if an individual has previously pulled the left lever down at any point in the past, then they should move the right lever.?

You, meanwhile, will be the only one who ever resets the left lever from position B to position A.

This gives you a way to count how many people have been visited by the robot.?

Everyone needs to pull the left lever down exactly once, and you’re the only one to pull it back up.

你主動(dòng)承擔(dān)了任務(wù)，在一切就緒的時(shí)候按下按鈕的任務(wù)，并給其他人下達(dá)如下的指示。

你將用左控制桿來計(jì)算訪問次數(shù)，而右控制桿沒有任何用處，所以，移動(dòng)右控制桿位置無(wú)所謂。

其他每個(gè)人都會(huì)拉動(dòng)左控制桿，從位置?A?到位置?B，僅一次。

若機(jī)器人出現(xiàn)時(shí)左控制桿已拉到?B，或某人已在先前某時(shí)把左控制桿拉到?B?位置，這時(shí)，他們應(yīng)該移動(dòng)右控制桿的位置。

而你，才是唯一重置左控制桿的人，從位置?B?重置到?A?。

這就提供了計(jì)算 被機(jī)器人訪問過的人數(shù)的方法。

每個(gè)人只需將左控制桿 拉到?B?位置?1?次，而你是唯一能將位置重置回?A?的人。

So you know that the tenth time the robot visits you with its left lever in the down position, it must have visited all ten of the others.?

And that means you’re safe to press the button and teleport everyone home.?

It may take a while– most likely the robot will need to teleport around 355 times; but better that than leave anyone behind.?

Your teammates phase back into your home dimension one at a time. The mission proves a great success.?

Well...mostly.

所以，當(dāng)機(jī)器人第十次拜訪你、且左控制桿處于下方位置 B 時(shí)，你就知道，它已訪問過其他所有人了。

也意味著，你可以安全地 按下按鈕，傳送每人回家。

這可能需要一段時(shí)間——很可能機(jī)器人要傳送約 355 次；但總比留下任何一個(gè)人要好。

你的隊(duì)友依次回到 你們家所在的維度空間，任務(wù)圓滿完成。

嗯……理論上如此。
