The weird thing about these types of videos is that visually you can see it work, follow it, and it appears simple. But there are likely pages of math computations that prove this out that never get shown. I'd never follow it, but I'd like to see the math behind it.

Huh, that's a neat solution. Mine was to use an iterator at the end of the line, but I'm not sure if that breaks the "finite poses" rule: - Build an arbitrary list of poses greater than the number of robots. - Robot 1 assumes the pose that says "I am number 1!" - Each idle robot looks to its right and assumes the pose one higher than that (unless right is also idle). - When you get to the end, you've counted all the robots! - The last robot (which sees a blank space next to it) begins ticking down through all the poses ("blank left & not idle = my pose - 1"). - Each other robot, when it sees a robot with the same pose on its left, ticks down one pose. - When the robots declare "We are number 1!" ("I am number 1 & left is number 1") they're ready to tick over into "Firin' ma lazor!".

Alright, let’s take out some math and see how long it would take. Seeing as the BPM is 15, one beat will take 4 seconds, so we will multiply the number of beats by 4 to get the time in seconds. We now check if 128 is a perfect power of 2. It is, being the 7th power of 2. We don’t need any double general rules. The first hand signal will take 3n/2 beats to propagate to the end and back to the middle. Our squad is 128 robots, so 3(128)/2 = 192 beats. Our squad is now split into subsquads of 64 robots. 3(64)/2 = 96 beats. 192 + 96 = 288 beats so far. Now we have subsquads of 32. But here’s where we employ a neat trick. Because our squad size has been divided by 2 each time, so has our number of steps to division. We can simply divide the previous number of steps by 2. 96 / 2 = 48 beats. We can verify this fact by also evaluating the old steps formula. 3(32)/2 = 48 = 96 / 2. 288 + 48 = 336 beats so far. Subsquads of 16. 48 / 2 = 24. 336 + 24 = 360 steps so far. Subsquads of 8. 24 / 2 = 12. 360 + 12 = 372 beats so far. Subsquads of 4. 12 / 2 = 6. 372 + 6 = 378 beats so far. Subsquads of 2. 6 / 2 = 3. 378 + 3 = 381 beats so far. Now we simply add 1, representing our final firing order, to get a grand total of 382 beats from start to firing. Now let’s evaluate the time in seconds. We simply multiply our number of beats by 4 to get 1528 seconds. Now how long is that in seconds _and_ minutes? One minute is 60 seconds, so we divide 1528 by 60, keeping the remainder as the number of seconds. We get our final answer of an insane *25 minutes 28 seconds.*

One thing to point out here is that since the state transitions of each robot only depend on their immediate neighbors, you don't have to have any knowledge of how big the pool of robots is. But if you added a little bit of memory, you could probably arainge it so that once the synchronization event takes place, every robot knows what their position in the line is, up to some limit.

I just wrote this out replying to a different comment, and it does work, and faster than the video's algorithm. You can just use a 128-bit number that guarantees it can store the number of computers in the system (64 bits is almost certainly sufficient and 16-32 bits is overkill in most real cases, but there aren't even 2^128 atoms in the observable universe, so it's guaranteed). Each robot has 128 "legs" with two states (representing a single 128-bit number), then the "hands" tell it whether the signal is coming, going or idle. So computer 1 gets the start signal, says "leaving", "1" to its neighbor. The neighbor sees "leaving", adds 1 to the count and propagates "leaving", "2" to the next neighbor. This proceeds to the last computer, which holds the final count of computers, "N". After the right-hand neighbor is set to "leaving", the current computer can return to idle or just sit in the current state. The final computer sees that it's final and switches to "returning", "N". The penultimate computer sees "returning" and also switches, but subtracts 1 from the current count to be "returning", "N-1". This repeats back to the beginning. The difference on the return trip is that after the state is "returning", each computer counts down by 1 every tick. So the "returning" signal will hit computer 2 when the count is "2", but every computer to its right will also have counted down to 2. As computer 1 sets its state to "returning", "1", computer 2 counts down once to "1" (along with all the other computers). Now, all the computers count down once to zero and fire. Alternately, they could all fire at 1, and computer 1 knows to fire next tick if the computer to its right says "returning", "2" this tick. For N=11, the video took 34 ticks, where mine will do it in 21 ticks (10 "leaving" ticks, then 11 "returning" ticks, since the last computer can transition from idle directly to "returning", "N" and skip the "leaving" tick). Even better is if whatever method you're using to synchronize ticks just counts all the computers each time and you can just store the total computers plus a given computer's place in line. Then *any* computer can originate the signal and start the count based on the farthest distance from it (a middle computer would start at N/2, for example). If one computer sends a signal after another already did, but before it knows about the signal, all computers seeing both signals can just use the lowest count.

Actually this is a real engineering problem. Its from computer science, and the practical considerations are (Surprisingly enough) in computers. When computers are involved, each machine can be far enough away that only adjacent machines on the network can talk, and synchronisation of certain tasks can be important. This is the engineering side of it. It's a bit like the two generals problem - its seems silly to talk about, and like its just a problem for the sake of logic and maths, but its something that actually needs to be considered when dealing with computer networks.

If every robot can measure time and can perform actions instantly, it should be pretty easy - every robot performs action exactly on beat, to act as a basic synchronous clock. Before starting the execution dance, they sync their clocks. The leftmost robot sends out a sync signal with no information. It gets passed like the "hand up" signal in the video, bounces back and comes back to the leftmost robot. Every robot automatically syncs their clock to the robot left of them. Only after leftmost robot receives the returned sync signal, the main execution dance begins.

i like how they have to get hit in the head with a squeaky hammer to activate

Why the leg has three stages: the hand signal must travel three times faster than the leg signal because it has to travel three halves while the leg signal only one so that they meet in the middle.

That's genius!! Thanks for explaining it to my stupid mind! Now I can truly appreciate the solution!

And multiple leg signals to handle even or odd amount of squad members since with an odd amount you will have a single person in the middle but with an event amount there will be 2 middle men

Its like a terrifying robot timer. You know its getting closer to shooting you, but you never know exactly when it will

This is also a decent example of how a resonance chamber works if you think of each limb position as a harmonic series

Imagine a army battle vs 2000 or so of these guys And the enemy is polite enough to wait for them to finish

"Alright, Alright, I'll Wait A Week For You All To Align.. -Sigh.- Someone Knocked The Middle One Over, We Have To Restart It."

The mathematical precision of them trying to decide when to kill you is so detached it’s scary. But also I want to dance

I keep forgetting about this video and then it pops up again in my recommended a random day

n=17 is my favorite. The pirouettes and the high notes make me giggle. Maths is beautiful AND deadly. I love it.

For some reason this is the funniest thing I've seen this week.

All the while, whatever was in the path of 100 robots decided to take a nap and then just leave

Everybody who would like to say something about what they have done this weekend please raise your hand. All the toddlers in kindergarten: 6:55

I thought about splitting the problem along the middle of the line, but I didn't think about sending a signal that is 3 times slower than another. Beautiful solution!

Thought this was going to be an impossible problem, but it wasn't. Very neat!

Wow, this is probably the most clever logic puzzle I’ve ever seen.

I think it would have been cooler ti split the firing state into multiple states, for aesthetic purposes only. A preparation state, an aim state, and a fire state, for example. Having the entire protocol being linked to firing will make it so that nothing is changed in terms of solution, as each step must be performed in order, while also making it so that the robots don't just make an ugly snap to firing. This also makes the protocol to be played to the beat. But hey, that's just me.

A classic divide and conquer approach. I love the solution, it's beautiful.

Two uploads in a century? God has blessed us

Wow, this is a really clever solution, and the procedural animations are impressive! Thank you!

Suddenly, Boston Dynamics teaching their robots to dance doesn't seem so innocent.

It looks like those Wolfram cellular automata, but with finite set of cells in the horizontal axis and with more than 2 states.

@Michael Darrow I know. But Wolfram studied the 2 states 1 dimensional and infinite cells cellular automata. The video shows us a 1 dimensional, finite cells and more than 2 states.

Such a fascinating problem and solution!

Here I was trying to solve the problem not knowing you could have a leg and a arm state separate from one another, you made it sound and look like it was all one state.

"I love these random educational videos from years ago this is from what? 6 years ago?" > Last week

The last bit with the music just had me smiling crazily and don't know why, it bought a lot of happiness

Thanks for posting. This is just about the proudest I've ever been of solving a logic puzzle. The crazy thing is that as complicated as the solution is, most of it is actually forced by the constraints of the puzzle. There are a few different ways of dealing with parity issues. But most parts of the solution are provably required.

4:56 when you find the nerf dart that you lost in 2010

I like how the music and the dancing is all cute to watch, but what they're actually doing is getting ready to kill you, since your point of view is that of the condemned. XD

uncanny how cheerful the video is for being about a firing squad

I could watch these full runs for hours. It's hypnotizing.

It's amazing to see how people can find ways to emulate things like memory and recursion in such simple and restricted systems like this.

The new rhythm heaven game looks amazing!

Good KZread algorithm! A video I would have never found but needed.

Pov you are a war criminal and are being treated to a funky robot dance

Lmao "this is a robot firing squad" being the first thing, sounds like Mark Zuckerberg and his buddies dislike my being alive.

This has to be the most upbeat tune I've heard while being executed by firing squad

Imagine being on the receiving end of this, just watching the robots do a dance number and knowing once all the robots finish you’re dead

I feel like I played Factorio in my head watching this

Woah, more than one video posted in a year? THIS IS AMAZING!!!

everyone gangsta till the robots start doing their funny dance

Executions in 2050: "The firing squad is ready when I find that video again!"

POV: You're in battle, rising against your robot overlords, climactically facing a large firing squad, and in your anticipation, they start dancing

mathematician: now do it in 2-D rectangle, or generalize to n-D hypercuboid.

2D: Assuming each robot can see the 8 neighbours around it, and that the lower left robot is the one that gets activated at the start, do the following: The robots on the lower row of the rectangle perform the hand and foot signals as shown in the video, up until they all turn into generals. The robots in the row above will notice that all robots below them have turned into generals. At this point, they will simply perform the exact same dance going vertically. Eventually ALL robots will become generals and they shoot. It should be easy to see how this can be generalized to any number of dimensions.

I have a copy of the 'Computation' book by Minsky-- college text book. This problem is basically the only thing I specifically remember from the book and it has always intrigued me. When I saw the video title I knew immediately what the topic was about. I'm still, to this day, curious what the 2n-2 step solution is. The book claims the soldiers in that solution have 1000's of states, but the link in the description says "Optimal solution: The fastest solution to this problem uses 2n-2 steps. There’s a proof this is the best possible time. It uses also only 6 states. It is not known whether this is optimal or not."

Everytime the robots shoot I'm hearing a friendly voice saying: "Now you are dead."

Everybody gangsta until the fire squad robots start dancing
