Interpret this sequence 1893 900 5 1040 ...

Postby xkcud » Mon Oct 10, 2011 5:46 am UTC

I came up with this today and thought it might interest others.

It does NOT use:
  • Any mathematical equations. This is a programming and detective work puzzle.
  • Fibonacci or other mathematical sequences other than the natural numbers.
  • ASCII or any other alphabetic mapping (though letters are involved in a way).
  • Words in any language.
  • Hexadecimal or octal.
  • Anything statistical, geographical, or pertaining to data collected from anything.

The puzzle is just to figure out what you are looking at.
There is one specific anomaly thrown in for this purpose -- if you find the correct answer, you will know how to answer this:
K = ?
(The anomaly should not affect your ability to decode the pattern)

The following is in decimal:
1893 900 5 1040 5 10 10 1 ...

is this the sort of puzzle that would elicit an 'oooOOO!!!' reaction when the sequence-generating-rule is revealed?

What was the sequence? Even with the full sequence I can't figure it out. You said it wasn't a mathematical sequence but I ran it through Eureqa (which uses genetic programming to find mathematical functions behind data) and got some interesting results. But it didn't figure out what the pattern was exactly and still is missing a lot of points.

Spoiler:
The simplest equation it gave me fits the graph decently: Y = mod(lastx, 1.455)*mod(lastx, 1.375)*mod(lastx^2, 79.61)

The best fitting equation: Y = mod(lastx, 1.376)*if(greater_or_equal(79*mod(lastx, 77), x), mod(105*lastx + lastx*mod(lastx, 57.06), -54), lastx)

(lastx is the previous value of Y, not x. My bad.)


What's weird about this is in all the equations it produced it only used lastx. It had access to x and the last 2 values of Y, but it only really used the last value. It also uses mod a lot and I have no idea what to make of that. Based on the puzzle description I guessed it had something to do with binary, and that might make sense of Eureqa using mod (I think.) It had access to a ton of other mathematical and logical functions and didn't use them at all.

Note: The best fitting equation isn't actually as complex as it looks. It just uses two separate functions for each half of the graph since the second half has some very weird and different behavior than the first half. Or at least that's what I think it's doing.


There is very clearly a pattern to it on a graph, and the functions pick up on it somewhat. They even predict or get very close to most of the validation points on the graph! On the other hand they miss many of the outliers and there are parts that aren't getting fitted very well.

UPDATE: It found an even better and simpler function: Y = min(1.476, p1)*max(p3 - 290, sqrt(p5)). P's are the previous values. I still can not make any sense of this though. Continuing to search for even better solutions.

UPDATE2: Apparently the pattern strongly correlates with the value about 240 before it. The best solution so far: Y = min(delay(p1, 240), max(delay(p1, 11), 2663 - n))

Also on a graph. there is definitely a pattern to it. There are straight rows of points at different levels with seemingly random points in between them.


If anyone can make sense of this or knows the answer I would appreciate it.

It's been a week. Time for a clue and/or the answer in a spoiler please.

There should be a rule against people posting puzzles without solutions and then leaving !

What if somebody breaks the rule? Make them leave even more? :)

They should be hunted down and killed like the dog they are! :twisted:

(More seriously, there could be a rule for this forum that all puzzles must have the solution spoilered in the OP - unless there is no known solution of course, in which case that is pointed out instead.)

I think we have to be more trusting than that. This hasn't happened a huge number of times, its happened once (by my imperfect memory). We could make a rule for this one case, or relax, and realise its not a huge issue. I, or course, favour the later approach.

I can also recall threads where people have posted puzzles and a week later admitted they made up the puzzle and had no idea what the answer was. That's no less frustrating!

If not a formal rule then it should certainly be good etiquette to make the situation clear up front.

edit: Btw, it's happened way more than once - it's not even the only instance currently on the front page! Here's a couple of the others still on the front page:

Simple solution for you, don't spend large amounts of time on puzzles by people with single digit post counts.

Meh, those code ones are tedious either way. Even when someone decodes it, they usually just start conversing in the code without a clear "answer" presented. Yet, the people who like those threads like that sort of thing, it seems to me.

But fine, I'll change a sticky or something to provide some guidance.

You said it wasn't a mathematical sequence but I ran it through Eureqa (which uses genetic programming to find mathematical functions behind data) and got some interesting results. But it didn't figure out what the pattern was exactly and still is missing a lot of points.


Two things are clear to me, without the use of any sophisticated software:

1. The sequence generally decreases.
2. The are long strings of numbers which repeat many times, sometimes in part and sometimes fully.

I think that ANY sequence which fills these two criteria, will show interesting patterns in Eureqa. But these patterns tells you absolutely nothing about the actual rule by which the sequence was generated by, or even if there is such a rule. For all we know, the OP could have made the whole thing up on the spot in order to troll us. After all, it isn't too difficult to create such a sequence manually using the cut/paste option of your favorite word processor.

It can't be that because a lot of the sections aren't perfect replicas of the previous section. Some sections could be copy pastes, but they each look slightly different. It's pretty clear when you look at it on a graph (is there any way I can post an image?) Try imgur slash GQxzujl. Notice how specific numbers appear a lot, and then disappear, in order from largest to smallest.

It's pretty clear even without a graph. Just by LOOKING at the numbers you begin to find patterns. And after 10-20 minutes with the "find" feature of your favorite word processor, the general structure becomes quite clear.

But I still don't see how this serves as evidence that the code is real. What's stopping the OP from doing a copy/paste and than manually changing some of the numbers?

I'm not saying that he necessarily did that. But it is a possibility. Especially since the guy wrote us this puzzle over 2 years ago, and we haven't heard from him since. I love playing around with codes, and I am kind of OCDish when it comes to codes I haven't cracked yet, but this kind of behavior from the OP isn't exactly encouraging...

EDIT to add:

Another thing that bothers me with this puzzle, is that the OP put seemingly impossible conditions on what the sequence generating rule may be.

He states that it does not involve words in any language or any alphabetic mappings, but then continues to say that "letters are involved in a way".
He also states that the rule doesn't involve any equations or sequences other than the natural numbers, yet it isn't based on statistical data or other information from anywhere.

Which seems to leave us with pretty much nothing, doesn't it?
