🧵 Puzzle 5 ( 2 in 1 again, Difficulty 3/7 A, 2.5/7 B)
John Puzzle at Fri, 21 Feb 2025 05:04:11 UTC No. 16594439
Instructions:
In each puzzle, 2 panels are missing.
You must select 2 of these panels—in the correct order—to complete the pattern. ( 46 is different from 64)
It is possible for the same panel to appear twice (e.g., “11,” “22,” etc.).
None of the puzzle require external resources. You do not need any special knowledge to solve these items. None of the patterns are cultural.
Lastly, you need to provide both the answer choice and the explanation. Feel free to use drawing tools to aid with your explanation. I encourage it so that it is clear to everyone what you are saying.

You nerdsniped the wrong CS fag. Second one is 56, the dots are differential coding.

I'm sure you can write a better explanation so that others understand.
Like wtf is differential coding and how is it showing the pattern by which black dots appear for instance?

>wtf is differential coding
LMGTFY.
To be excessively specific in regards to the puzzle itself, the differential coding is done left to right and top to bottom respectively for the two dot patterns, independently per row/column, with the first black square representing the start of the signal and the initial state being white.

Fair enough. You can take the solve.
I will post a more comprehensive solution later.
Good job.

you must either have looked at a lot of differential coding in your life or you are giga brained. even after i googled and understood differential coding i never would have gotten that individual row then column thing in a million years. also its slightly different with 1+1 making a solid black and then thereafter but i understand enough to solve them. gj anon

wdym, I solved it without knowing what differential coding is in a couple of minutes. Not to flex or anything, but I didn't think it was that difficult.
A lot of my friends got it about as fast too.
What's your opinion of this one:

i got that it was two shapes meshed together but i couldnt suss out the number of connecting edges. the only one of these i solved alone was the second one you posted. im guessing you get your friends from some community involved in maths or puzzles

yeah, I see your point. I got too used to them I lost some perspective. They are smart and also have experience with puzzles so it makes sense.

how much do you think these things are innate horsepower and how much is being used to puzzles?
John Puzzle at Fri, 21 Feb 2025 07:13:01 UTC No. 16594503
>>16594501
for me it is like 50% being used to puzzles 50% innate. My iq is around 2SD based on some professional tests and OLD SAT forms(although subjectively i feel around 125 sd 15), but I've seen many people with the same scores as mine struggle with them. I imagine I would struggle a lot if it was the first time I was exposed to these matrix puzzles.
It depends. What I'm sharing here is quite novel so normal experience even with matrix puzzles won't help too much.

To add more.
It takes me a while to solve hard codeforce puzzles because it is a thing I don't have much experience with. Sometimes I get stuck on 1600-1800 elo problems and anything past 2000 elo can take me a 1-6 hours if I even get to solve it.
I did not do a DSA course, I mainly learned DSA by doing puzzles on leetcode and codeforces. I'm used to bashing my head on problems for hours.

For puzzle A, the only potential solution I've found is to follow the number of inscribed right angles in the shapes. The first row has 1, 3, 4 inscribed right angles. The second row has 3, 2, 1 inscribed right angles. Since the number of right angles is either strictly increasing or strictly decreasing in each row, that leaves piece 2 then piece 4 as the only solution, creating a bottom row of 2, 3, 5 inscribed right angles. The other pieces have 0 or 2 inscribed right angles which cannot create a strictly decreasing or increasing trend.

I think it's literally 99% mental tools. Intelligence can determine how easily you acquire models and how fast you can apply them, but you have to have the right model to solve a given puzzle. If you don't, it can take a very long time or even be impossible to discover it indepdendently, and even in that case your current models provide the required basis for extrapolation.
John Puzzle at Fri, 21 Feb 2025 07:27:33 UTC No. 16594512
>>16594510
Not exactly, there are people with a lot of experience that are just unable to crack some of these.
At the same time I've seen people solve very difficult problems fast without having and experience with the topic or anything tangential.
There are some exceptions where moderately smart people got very far through acquiring these mental models, but it doesn't happen to everyone and it doesn't necessarily happen in a general way.
Another fun fact:
I IQ tested a bunch of high elo codeforcers (2000+ elo). I notice that they all had an Iq over 130 sd 15, but as you increased in elo, the IQ didn't exactly grow much on average. There seem to be some thresholds for G that are required to develop specialized skills/intelligences.
I could be wrong tho.

It isn't related to angles.
Anonymous at Fri, 21 Feb 2025 07:49:08 UTC No. 16594530
This is what I could come up with:
The number of lines in each square is a palindrome across the center square (i.e. 2, 3, 2 or 4, 3, 4) so the eighth square has to be an answer with 5 lines to make 5, 3, 5, and only one answer has 5 lines so the first answer is 1.
The second answer is 2 because the line of symmetry should be from the bottom left to the top right of the ninth square.
Also I don't do puzzles and am actually diagnosed with schizoaffective disorder and am low IQ so this is the best I can do.

It's a good attempt, but it isn't that.
The pattern actually doesn't involve counting this time.

>>16594439
A is 5 and 1
The axis goes
/\|
|/\
\|/
Also in that way every row and column adds up to 11 (number of lines).

Congrats, that's it.
There is another pattern that further motivates 51 involving symmetry, but it isn't needed

I see, that's neat. I knew it was about symmetry, but I didn't see how the shapes were similar. Every idea I tried fell apart with mid right.

It's okay to admit you were wrong. Not everyone can be as intelligent as I am. And at this high of an intelligence, it can be hard to problems of this difficulty.

You are inconsistent in how you decide what makes a letter. Sometimes you take the entire shape sometimes you take half of it. Not to mention for half of the shapes it is very questionable and just loosely resemble letters with mid right not looking at all like the letter A.
I know you are being an asshole troll and you are going to pretend that the schizo shit you posted is somehow better than the actual solution which not only was validated by getting a point for in on the test it used to belong to.
Literally anyone can tell there is a loose letter resemblance but would dismiss it upon further investigation.

ok after thinking for a while here is why 56 is the answer for B(though I'm sure the logic isn't exactly what the puzzle maker was thinking)
first set of dots matches height of the first black square in the matrix. this gives 1, 3, or 5(green)
second set of dots matches length of row from the first black dot. this gives only 6(blue)
you can use the second col in the first matrix to see that only 5 can work(purple)
John Puzzle at Fri, 21 Feb 2025 14:47:35 UTC No. 16594848
>>16594826
Looks right to me.
In mean. The whole idea is that the first black square determines the height of the circle tower and the 2nd black square has everything below it as well as itself colored black on the circle side. on column 2 this logic applies vertically and on column 3 it applies horizontally.
Is this not what you mean?

>>16594848
oh I get the logic of the second black square now. I saw that 2 rows had the same arrangement on the input and that led to the same output and used that to narrow down the answer
fun puzzles btw even if I only get halfway there on them
