    @Baz Snell Yeah, the Americans bastardise (with an 'S' btw, not a 'Z'!) the English language to an unbelievable degree. They even make up complete words which don't exist! eg, they continually say Aloominum, when the material they're trying to talk about is Aluminium! There is NO SUCH THING as Aloominum - Yanks, it doesn't exist! Same with Solder, used for Soldering wires etc - they say Sodder!! No such thing guys. There's an 'L' in there - don't you see it? Rant over:-)

    The reality is that super-computing this into infinity would run for decades, and that's the only way you're likely to have a chance to find THE number that is the counter. This is a level of calculation that we will still be trying to solve when we reach Star Trek - level physics in our space programs. And that's what makes it great: all of our advances in math and science and technology have been built on the supposition that anything can be solved, if we are smart enough, dedicated enough, patient enough, creative enough, even wealthy enough to finance it all. Just look at the recent helical drive material that supposes to push us right to the edge of the speed of light. It all takes passionate people to make all this happen. And videos like this are amazing, because it breaks simple-yet-not-so-simple mathematical dogma into digestible pieces that the average person has a chance to grasp - maybe not entirely, but enough to be intrigued. Kudos to Derek Muller and Alex Kontrovich for executing this lesson perfectly. Not everyone has the skills and personality to pull it off this well. And a special kudos to the animators who visualized these concepts so beautifully, too allow the average viewer that chance to grasp them. I learned the Collatz Conjecture briefly as a thought exercise in college, and it never went very far, for obvious reasons. Thanks to this team for reminding me how interesting it is, and how unlikely we are to ever solve it anytime before aliens colonize Earth and bring us more advance math.....

    Lol i remember hearing about this in grade 11 but had enough of solving for x definitely sounds like an energy or scienece issue. Math has always been a language for me. Cool to know we tried negatives. Wondering if we used another odd prime and not 3 but 3s never involved how is 6 divided by 2 not an oçcurence. Either way i spent alot of time doing other patterns. And if you can relate it to energy and 1 being state of zero energy just gotta find vrelatinships between numbers and atomic weights possible. Math is definitely universal obviously enjoyed the video. Wish i hadtime i mean it is a quarantine but... sorry just remembered if you got 3 youd be increasing again for 4 more

    I was thinking similar - but probably not. I'm guessing there could be a cycle where it doesn't have 2^n in its cycle (in which case it would decrease to the smallest positive integer 1). Is one way to think about it - that there will be sufficiently large 2^n that ever odd number will reach in its life cycle? (7:58) We could try expressing the fraction of odd numbers that end up with 2^n somewhere in its path and add them together? I'm guessing the guys who've been researching this probably are in a better position to answer this though. Perhaps that's why it's a conjecture not a proof. Also, if this is as simple as that - I guess there won't be a department mathematicians who haven't solved it for 20 years.

  • Duckbang

    i was wondering, could one possibly solve this conjecture by proving that all sequences will have a power of 2 (8,16,32,64 etc etc) in it? because the moment we hit a number of the form 2^n the only thing we can do is divide by 2 till we hit 1, because a power of 2 will only have 2 as a factor and thus be even until we reach 1, where we will hit the loop. I'm pretty sure epople have already thought and tried this, if so, what went wrong?

    Feel like the answer ultimately has something to do with powers of 2. Like the counterexample will inevitably be a loop that just barely misses a power of two, or it turns out that every possible power of two is reachable via 3x+1.

    Every other exponent of 2, when you subtract 1, results in a multiple of 3. 4, 16, 64, 256, 1024, 4096, 16384, etc ad infinitum. The probability that an even number, when reduced by a factor of 2, will result in an even number is 50%. But the probability that an odd number multiplied by 3 and then plus 1 will result in an even number is 100%. A downward trend is to be expected because the probability of reducing by 2 is twice as high as the probability of multiplying by 3. As the number trends downward by a factor of 2, the probability of the eventual 3x+1 operation resulting in an exponent of 2 increases exponentially. Once the result of 3x+1 is an exponent of 2, the game is over.

  • Svela Prisera

    While it might not be of any importance, I was playing around with the Collatz Conjecture's equation after watching this. By messing around with the value that is added to 3x I think I've determined that you can add any of the first five odd numbers and it will seemingly always create a loop, although I only tried a few numbers for x so I'm not entirely sure. Anyways, let's say I do 3x+3 instead of 1. No matter what number x seems to be, the equation will eventually create a loop that ends with 3 instead of 1. This seems to be true for all the other prime odd numbers up until 9, with larger numbers for x simply taking longer to get to the loop like with 3x+1. +3 ends in a loop of 3, +7 ends with 7, and +9 ends with 9. However, for some odd reason, while 1, 3, 7, and 9 all create a loop ending in the numbers added, 5 doesn't always loop back to 5. Sometimes it loops to it's added number, but other times it instead creates a loop that ends in 19. I don't have enough knowledge with mathematics to understand why 5 is such an exception to the other numbers, but it doesn't want to loop back to it's added number as consistently as the other numbers. Now, with all that said, I don't know how true all of this is. I am not an expert in this field, and I was just messing about using the information given in this video. If anyone would like to correct me then by all means feel free.

    I think everything you said is accurate, but unfortunately it doesn't help a whole bunch. To solve the problem you either need to find a way to completely prove that every number will go to 1 or that there is at least one number that doesn't go to 1. The likelyhood that there is a number that won't go to 1 is very unlikely since numbers are infinite, so they can just keep going up until they inevitably come back down. But that doesn't matter if we can't actually prove that every number doesn't work, and we can't just try every number.

Lastly when you look at the charts not numbers but all those dots, it looks just exactly the same in patterns that it could be that with all the numbers checked thus far it could be accurately assumed the it won't stop the same patten

    @Kicky my sister believes she has dyscalculia, although she was never evaluated and diagnosed for it. Honestly, since I have some learning disabilities myself: Autism, Amblyopia, and Mild Cognitive Disorder, which slightly affects my brain's processing speed, have all hindered my ability to learn, so at this point, I don't doubt that's a real thing. However, even someone with dyscalculia should be able to make improvements after enough practice; it won't be easy of course but I don't think it's impossible. I'm fortunate to have an Autism spectrum disorder in the sense that I gained an early interest in math; otherwise, I'd be pretty terrible at it too. Despite this, I also had to work really hard to learn it at times; It didn't always make sense right away with little to no effort. Has it helped me? Perhaps it has indirectly. I'm not making money solving math problems all day, but software development involves quite a bit of critical thinking so I think math certainly helped my brain develop those skills.

    The only possible demonstration is by induction, so we initially tried to figure out how to partition the problem. Of course, sequences starting with even numbers can be ignored, and demonstrating that all the numbers in from 3n+2 are always present in lower sequences is relatively easy: example 5 appears in the sequence 3;10;5. 3n are always "primitives", so they never appear in previous sequences, but we can demonstrate that all the 3n obey to the conjecture. 3n+1 are more tricky. But what happens in functions with more than two choices? We found another unresolved problem that was analyzed by Collatz, called g(n). This function divides by 3 instead of by 2 and rounds the result up or down to the next or previous multiple of 3. So we started wondering how functions with an arbitrary number of choices behave and we have found the reason why the Collatz conjecture must be true. It's all detailed in a PDF, but before finding somebody interested in reviewing it, my friend passed away for a bone cancer. I would like to have it reviewed in his memory, even if it's found wrong. A hint: collapse the two operations on even numbers to a single (3x+1)/2. Comparing its behaviour with that of the functions with > 2 choices is easier.

    11:27 "If you can show that in every 3x+1 sequence there is a number that is smaller than is smaller than the original seed then you have proven the Collatz Conjecture." Wouldn't that mean that a loop other than 421 is impossible? That the only way for it to be false is if it would approach infinity?

    Every integer number above 9 can be expressed as a sum of the preceding decade number +10. e.g. 11= 1+10 ; 21= 11+10, 12= 2+10, 47= 37+10, 1345 = 1335 +10 etc. If a mathematician can prove that by adding 10 to any number the sequence must be a always eventually return to a value less than the preceding number and therefore result in the sequence 4,2,1 . Run the sequence on the number nine. Run the sequence on the number 10. Show that the addition of 10 adds a defined specific value to the sequence. Then for any integer number you can demonstrate that the sequence outcome is the previous decade plus the sequence for the number 10. Why can't they do that?

    Infinity does not work with this. Take infinity as an odd number, you multiply infinity by three and then add one. It’s still infinity. Take infinity as an even number, so infinity divided by two is half of the infinity which is still infinity.

    The reason the strings behave differently on the negative number line is because +1 takes the string in a different direction on the negative side of things. They will still end up in one of three possible known loops, as far as we know, but they move through thought-time with a different motion. Do that seaweed-looking rendition with the negative numbers. The paths move differently.

    This is the same patterns you'd find when you map primes. Could it be related? Because the factors that impact 3x+1 is whether 2 is a prime in the number within the original pick, or when a prime of 2 would come back up in the sequence (which makes me want to do math), only large unique prime combinations could increase significantly (e.g. 27 which is 3^3), so then the proof lies in the nature of if there are any large prime combinations that would become unbound by the dampening of the 3/4 reduction to introduce a factor of 2.

    Have they looked at the pattern creation in binary? If the least significant bit(lsb) is 0 then shuffle all bits down one place, if the lsb is 1 the place a 1 in the column ahead of all existing 1s & set lsb to 1. Seeing an infinite pattern looks easier to me like that but I’m not a mathematician so maybe I’m severely missing something…

    With `c3` being the first lower value in the trajectory of `c2`, a stopping (AKA dropping) pattern can be derived: ``` 2^p2*i+c2 -> 3^p3*i+c3 (i >= 0) ``` `(p2 >= 2, c2 odd, c2 For example `[7] -> (22,11) -> (34,17) -> (52,26,13) -> (40,20,10,[5])`, and 5 is less than 7, which involved 7 divisions-by-2 and 4 multiplications-by-3. The "+1 part" remains inside the `c2`/`c3` values. This means that the first lower value of any `(2^7)*i+7` is `(3^4)*i+5`, so `128*i+7 -> 81*i+5 (i >= 0)`. Example for `i=1`: [135] -> (406,203) -> (610,305) -> (916,458,229) -> (688,344,172,[86])`.

    I also add that the 3x+1 sequences end in a loop 1-2-4-1. There are only 2 possible endings for a sequence: loop or grow to infinity. The only possible loop is 1-2-4-1 (or 1-2 if we collapse the two consecutive operations on even numbers to (3x+1)/2. Now let's make a function with 3 choices: if N = 0 (MOD 3) then N=N/3; If N = 1 (MOD 3) then N = (N-1)/3 IF N = 2 (MOD 3) Then N=(N+1) MOD 3 Then let's vary the coefficient of the decrement: so that N = 0 (MOD 3) then N=N*2/3. Those two functions behave very differently: In the first, there are no crossings: Each number belongs to one and only one sequence. Some sequences end in a loop, other grow to infinity. There are only 4 possible loops: 1-1-1... ; 2-3-2-3-2-3 ...; 4,5,7,9,6.. and one longer starting with 44. The second function behaves very similarily to the 3x+1. Let's call "base" the number of choices. If the coefficient is >=base/2, the sequences have crossing and all end in a loop otherwise some grow to infinity and there are no crossings (crossing="numbers can appear in more than one sequence").

    So, here's the thing about these rules. Multiplying the odd number by an odd number is not a big issue. The division of whatever you get by 2 will obviously result in decay. The result of opposing multiplication of living cells is the opposite of what you get when life proceeds uninhibited. The ending sequence looks like 421. It isn't. It is, but it is incomplete. The digital root opposite of 421 is 578. These are opposites in terms of wedding up to 9, the highest single digit number in base 10. 4 and 5, 7 and 2. 1 and 8. The master is 124, the mirror is 875, going forward. 124875 comes out of 1 2 4 8 16 32 and so on. If you know how to use that. Cell multiplication. Check out the last six numbers in the longer decays. Read backwards, they are 124875. The rest of the effects are due to the interference of increasing the numbers by the highest possible number 3. There's the first bit of gobbledygook. It works for all of those numbers. 295 quintillion numbers.

    I think the question is "Why does this happen?" Well, any number which this rule had been applied, will eventually become a full frame number of two. Since by adding 1, you make the number even then by dividing it you eliminate an option and start off with another one. By eliminating all the options you eventually get a full frame number of 2, which will get you to 1 - 4 loop. That's why this situation occures.

    @Varitasium, I think, it has the simple explanation of its solution that it will always fall back to the loop. Just because we are looking for one series only and just ignore the other series hidden in it. Whenever the power of 2 numbers meets with 3N+1 numbers, it will fall back to the loop. The 3N+1 has to meet with the power of 2 numbers due to its nature. So we don't need to look for any bigger number as explained in this video. It's just a pattern number involved with randomness. This is the final solution.👍

    This seems less like a math problem and more like a programming problem. It's like using a a while loop with 2 if conditions. Honestly if you can solve this problem, you instantly make programming insanely efficient. Less loops means less operations required to complete a task, which means less cost (time, money and energy) to complete a task. Also if you want the negative side to have the same loop as the positive side and vice versa, just use these 2 rules. 3x-1 (for odd) /2 (for even) If you use +1 in the negative side you will practically have a different effect.

    Often times the simplest answer is the best answer. 1) the high end can scale infinitely 2) the low number hits a low at one (can never go lower that happens to put it in a loop) Conclusion mater how high the number goes. Infinity it can always go higher but when it hits its low it can never go lower and placed in a loop Also the loop is more likely to happen at the low end far less variables as for the high end far many more variables (infinite) I couldn't see how this would stump many.

    What's also interesting is what happens when you change the rules slightly. When picking the number, instead of applying 3x+1 for odd numbers and x÷2 for even numbers; apply 3x+1 for both odd and even numbers. If x=1, then 3(1)+1 =4. So now the rule for even numbers applies and eventually end up with one. 4÷2=2 2÷2=1 If x=2, then 3(2)+1=7. So now the rule for odd numbers applies and eventually end up with one. 7(3)+1=22, 11(3)+1, 34÷2, 17(3)+1, 52÷2, 26÷2, 13(3)+1, 40÷2, 20÷2, 10÷2, 5(3)+1, 16÷2, 8÷2, 4÷2, 2÷2, 1. When x=10 and x=18 it takes a lot longer to reduce to one, but eventually does. I've only went as high as x=20 by hand. What was also interesting was that the pattern of reduction for odd and even numbers eventually became the same.

    I like the nr 9. It has so many strange constant patterns. Pick a nr between 1 and 9 and keep adding 9 to it. The outcome will always return to the nr you started with. 4+9=13 1+3=4 13+9=22 2+2=4 22+9=31 3+1=4 this goes on. Another one with nr9 is, pick any nr and do it x 9 like 6473x9=58257 now add all the numbers from the outcome to each other 5+8+2+5+7=27 and this makes 2+7=9 and you can do this on and on but will always return to 9. If you start playing with this then you will see more strange constants in the outcomes. Sorry for my chaotic comment.. I find it hard to express this without the numbers.. :P

    Cant you prove it by looking at the pattern at which either 3x+1 is used for odd numbers and x/2 for even numbers? After all, the prime reason for such directed graph phenomena to occur is due to the varying time the rules for odd and even number is used. lets use 341 in your example: the number 341 has used the rule for odd number (3x+1) once, while it used the rule for even numbers (x/2) 10 times Then use the number 26, it has used the rule for odd numbers (3x+1) twice, while it used the rule for even numbers (x/2) 8 times Of course the magnitude of the number should be taken into consideration when proving this conjecture.

    In theory the context of dollars might not be enough either due to ultra hyper inflation that results in the dollar being so worthless that 2^68 dollars is an insignificant amount. Granted, at that point we will probably abandon the dollar as a currency, but theoretically it is still possible. So what I would change it to is specifically "the current dollar" just so it avoids this theoretical pedantic rhetoric :]

    @Matthew Talbot-Paine they would be a lot of digits of pi to be fair, in any application you will never need that many. For the sake of being able to generate them? Yeah, any number of digits is not even close to the size of the true amount of digits there is.

    I can actually solve it... Bro it's very simple. It equals 7 😁 Very easy and simple... It's not a Times symbol it's a X symbol in math So if you use 3X+1 the strategy is 3×1 =3 +1=4 4+3=7

    Can we use fractions instead of whole numbers? Because if we can, i.e. ½, then (½x3)+1=1½. So we continue to divide by 2 because we pay attention only to the denominator, and basically we never get number 1 as a result, but a +infinity. Of course, that is if we are allowed to use fractions...

    Yes but doing that is just automated brute force. We need something else; I think maybe a quantum computer; if nothing else it would be an interesting test of the a different computational matrix then the more common 0 and 1. Maybe this line of thinking is just my curiosity thou, basically throw everything we have at a problem, haha.

    Here is a question: Has the Xn + y space been explored much? Basically asking which sets of X and Y behave like 3 and 1, and which behave differently What if you change the Evens rule to be something other than divide by 2? What I think might be achieved by that is that if we find sets of numbers for which the patterns are wildly different, with multiple loops, or diverging sequences... but then if there are many which behave just like 3n + 1, but maybe they have 1 or two diverging strands, it might give us a clue where in the number sequence to check for a diverging sequence in 3n+1

    There is a stucture which includes every positive integer and shows that all converge to 1. It is of infinitel size but, throughout, any integer can be shown to be part of a regularly repeating pattern of formats.

    3x+1=0 Subtract the 1 on both sides which will give you 3x=-1. Divide the 3 on both sides which then will give you the answer x=-1/3.

    Once it hits 2^n then it will be down into the loop there is no limit to n so eventually you'll run into one and then the number would go into the loop.

    The seed doesn't follow the pattern. All numbers in the sequence, sans 1, follow the pattern. There's actually 2 patterns. 3x + 1 and halving. Applying the pattern to even numbers is inconsistent. I would first break this up to only analyze odd numbers as seeds. Then perhaps individually apply the 3x + 1 formula to all odd numbers within range. These microcosms will give you the ability to predict the combo. This is just what a programmer would do
