Here's a hint:

Most programming puzzles involve giving instructions to a single actor

大多數編程難題都涉及到給一個演員下達指令。

so that they can accomplish a goal.

以便他們能夠完成目標。

Instead, here we have a swarm of individuals,

相反，在這裡，我們有一窩蜂的個人。

each of whom can follow basic instructions.

每一個人都能遵循基本的指令。

That's unusual in programming, but not unheard of;

這在編程中是不常見的，但也不是沒聽說過。

researchers are currently experimenting with swarms of small robots

研究人員目前正在嘗試使用成群的小型機器人。

to do things like conduct search and rescue missions.

來做一些事情，比如執行搜救任務。

The prisoners aren't robots, but for Ethic's purposes they'll act like them.

囚犯不是機器人，但為了伊蒂克的目的，他們會像機器人一樣行動。

And by working together they can achieve their goal much more efficiently.

而通過合作，他們可以更高效地實現自己的目標。

Because you have a lot of prisoners, you'll want them to cover a lot of ground.

因為你有很多犯人，你會希望他們能覆蓋很多地方。

This matches up well to a maze-mapping technique called a depth-first search.

這與一種叫做深度優先搜索的迷宮映射技術很匹配。

It's called that because it involves going as deeply down a path as possible

之所以這麼說，是因為它涉及到要儘可能深入到一條道路上。

before going back.

在回去之前。

In other words, if you had a maze like this,

換句話說，如果你有一個這樣的迷宮。

you'd want to explore all the way down one of these branches

欲窮千里目，更上一層樓

before returning to this intersection and trying another.

在回到這個路口，嘗試另一個路口。

Everyone needs a clear set of instructions for what they should do.

每個人都需要一套明確的訓示，說明自己應該怎麼做。

Like — first, tie down the loose end of your wire by the crystal,

就像--首先，把你的電線鬆散的一端綁在水晶旁。

so it leads back there.

所以它導致回到那裡。

If you find the door, open it and hand your spool to Ethic.

如果你找到了那扇門，打開它，把你的轉軸交給Ethic。

If you're in a passageway, keep going until you hit a dead end

如果你在一個通道里，一直走，直到你遇到一個死衚衕。

or an intersection.

或十字路口。

But what happens at either of those places?

但在這兩個地方都發生了什麼？

If someone encounters a dead end,

如果有人遇到死衚衕。

they should backtrack to the last intersection.

他們應該回溯到最後一個十字路口。

But they also need to mark it, so no one wastes time and goes back there.

但他們也需要做個標記，這樣就不會有人浪費時間，再去那裡。

The best tool for that is the wire—

最好的工具是鋼絲

one option is to break both sections that lead down the dead end path,

一種選擇是將通往死衚衕的兩段都打破。

and tie the spool to the wire that leads back to the crystal.

並將線軸綁在引回水晶的電線上。

The broken wires tell everyone else who gets to this intersection

斷了的電線告訴所有到這個路口的人。

“Don't go this way.”

"不要走這條路。"

They'll also guarantee the final path will lead straight to the crystal,

他們也會保證最後的道路會直通水晶。

rather than visiting dead ends.

而不是走訪死衚衕。

Ok, so let's say someone's at an intersection.

好吧，所以我們說有人在十字路口。

Now which way should they go?

現在他們應該走哪條路？

The first priority is to have everyone cover fresh ground

首要的任務是讓每個人都覆蓋新的領域

to minimize doubling up.

以儘量減少雙倍的增加。

So if there's no wire down a direction, go that way.

所以如果一個方向沒有電線，就往那邊走。

If there are multiple choices, choose one at random.

如果有多個選擇，請隨機選擇一個。

What if they're in a sub-section like this, with 3 marked dead ends?

如果是在這樣的一個子欄目裡，有3個標記的死角呢？

The only thing to do is to go back where they came from.

唯一能做的就是回到他們來的地方。

We now know that this whole section is one big dead end,

我們現在知道，這一整段是一個大死衚衕。

so they should break and retie the wire when they get to the next intersection.

所以他們應該在到達下一個十字路口的時候把線斷掉再重新綁上。

But let's say they get there, and find two options where someone's exploring,

但假設他們到了那裡，發現有兩個選項，有人在那裡探索。

but no one's hit a dead end yet.

但還沒有人進入死衚衕。

They may as well choose at random and go help explore that path further,

他們不妨隨意選擇，去幫助進一步探索這條道路。

in case it's the right direction for the exit.

以防是出口的正確方向。

This isn't the only way to solve this challenge, but in any correct method,

這不是解決這個難題的唯一方法，但在任何正確的方法。

someone will eventually find the way out.

終究會有人找到出路的。

The moment of truth will be when Ethic takes their wire and follows it back,

當Ethic拿著他們的竊聽器跟著回去的時候，就是真相大白的時刻。

inward towards her goal.

向她的目標進發。

The great thing about this method is that Ethic's path is straight and true.

這個方法最大的好處是，伊思克的道路是筆直的，是真實的。

The maze doesn't have loops, so there's only one path from door to crystal.

迷宮沒有迴路，所以從門到水晶只有一條路。

And because everyone has been breaking and retying their wires,

因為大家都在斷線、重扎。

Ethic won't go down any dead-end paths.

倫理不會走任何死路。

Face to face with her creation, Ethic has a choice:

面對自己的創作，伊蒂克有了選擇。

she can destroy Hedge, or set things right.

她可以毀掉海傑，也可以糾正錯誤

All of this destruction was her fault, not Hedge's;

這一切的破壞都是她的錯，不是海傑的錯。

it was her oversight that instructed him to build an infinitely large maze.

是她的疏忽，訓示他建造了一個無限大的迷宮。

His decisions were misguided, but everything he did,

他的決定是錯誤的，但他所做的一切。

he did to follow his programming.

他是為了遵循自己的程序而做的。

Ethic accesses his core and fixes her error with a single number:

Ethic進入了他的核心，用一個數字修復了她的錯誤。

the size the maze was supposed to reach.

迷宮應該達到的大小。

Ethic has prevented catastrophe

倫理避免了災難的發生

and regained possession of the World Machine.

並重新擁有了世界機。

Her work with Adila, Octavia, and Lemma has already started to help people

她與阿迪拉、奧克塔維亞和萊瑪的合作已經開始幫助人們。

and heal the world's turmoil, but there's much work to be done.

並醫治世界的動盪，但還有很多工作要做。

With the forgetting food out of their systems,

隨著忘食出他們的系統。

the people will become themselves again.

人民將重新成為自己。

They'll regain their will to create and progress.

他們會重拾創造和進步的意志。

They'll be free to break down the walls they've built between each other.

他們可以自由地打破彼此之間的隔閡。

And they may come to approach their future with a little less greed

他們可能會少一點貪婪地對待自己的未來。

and a little more... Ethic

還有一點...倫理
