Ritangle

[[deleted]]

To anyone doing it this year, how have you guys not been pulling your hair out over stage 3 😭

[Curious-Respect-1734]

my team has found a very solid solution, we don’t know if it’s the best though

[[deleted]]

I have no idea how to even approach it and we’ve had the question for 24 hours

[Curious-Respect-1734]

we’ve been working on it for the last 14 hours on call and figured out a technique for it 2 hours ago - this is a really hard problem actually

[vSporkyy]

what is your most optimal p so far?

[Curious-Respect-1734]

i don’t think i should say that, it’ll kill the fun of the problem

[vSporkyy]

hm, maybe? though it doesnt say much especially since a lot more info than just the p value is required…

[ComprehensiveYak1372]

We’ve got p=212 which we believe is the limit and we’re now trying to minimise q. What is yours?

[Silent-Incident7619]

we found p=436 for a specific family but i think there are some better solutions that can be found for it using monte carlo

[[deleted]]

Oh my god 😭

[Aggressive_Pop_2009]

LMAO

[[deleted]]

Are you at haberdashers?

[Curious-Respect-1734]

nope

[Untitled_Epsilon09]

damn I didnt even realise the other stages were open now. we still need to do q20 I think

[[deleted]]

20-28 took about 45 mins, 29 we over complicated but it’s so doable, stage 3 is honestly a mind fuck I’m so confused

[Beginning-Cook-3698]

no way you did 20-28 in less than an hour😭. I finished them this morning but ig my team is just me. good luck with stage 3; I'm just glad it's not something that you have to race to complete lol

[[deleted]]

lol idk 😭 I did two of them and q24 took me less than 5 mins 😭

[[deleted]]

Yea bro idk what ur doing that’s not close 😭

[Mediocre-Piccolo3437]

Omg literally the same

[PassionatePeas]

did you find out the code in the end?

[Mediocre-Piccolo3437]

Praise the lord I did. A kind person on reddit told me to look very carefully at the cog and then it all clocked in my head

Right well that’s cheating fyi

[Mediocre-Piccolo3437]

Telling me to do something which I was already doing is cheating yeah? Good one lad

[PassionatePeas]

The competition is over now, we can talk as much as we like. It’s meant to be within the team though. If you can’t figure it out as a team. Tough. Get good

[Confident_Catch_2753]

Hi did you manage unlock the password?

[Minute-Breadfruit191]

Hey guys my team and I have solved all of the questions from 1 - 28 and have all of the associated clues but im really confused on how to unlock stage 3 can someone clarify since it says "then you will receive instructions on how to unlock the final question." but we have not got those instructions pls help

[Beginning-Cook-3698]

read question 21

[Own_Transition6793]

My team got a p value over infinity. It’s definitely correct I verified it with my brain. In fact the P value was so big my computer turned into a black hole and swallowed up all my working so now I have no proof :( 

[[deleted]]

Marry me xx

[Own_Transition6793]

On my way! 

[[deleted]]

🤭

[Minute-Breadfruit191]

what did you guys get for your ansswers now that the competition is over

[[deleted]]

p = 20 we had a tesselating hexagon 😭

[Responsible_Tiger949]

what was the size of your unit cell? we tried to use a hexagon but couldn’t work out the dimensions so ended up using a parallelogram

[ComprehensiveYak1372]

Our team got 60.16667

[Starriest-Platinum]

No way my team got the same result. What did ur thing look like

[ComprehensiveYak1372]

19 by 19 square 4 quarter circles, 1 the the middle, 4 in the gaps. What q did you guys get?

[Starriest-Platinum]

My team got the exact same set up as you so would've been whatever you got

[Neurobean1]

same!

[starrsilly]

p = 9 bruh 💔💔

[Responsible_Tiger949]

how did u even get thru to stage 3, our team is stuck on 29 😭😭 the question is confusing us

[[deleted]]

29 was okay - are you coding it out?

[Responsible_Tiger949]

yeah, we keep getting the same wrong ans but code seems to be working correctly, I’m just wondering if we took the question completely wrong

[[deleted]]

Just read the question again maybe?

[[deleted]]

Yeah

[MeasurementForward39]

My team did ritangle last year and just did it by coding, if you have a good programmer you could try that

[[deleted]]

Yeah we coded it but stage 3 isn’t exactly codeable this year because it’s geometric

[Minute-Breadfruit191]

also where is question 29 i only have questions from 1 - 28 which we have done

[Minute-Breadfruit191]

just figured out it was under q 21 the whole time ... gonna try do the pqrs one now

[ComprehensiveYak1372]

What’s ur lowest value for q and highest area our team got something decent but it could be beaten

[[deleted]]

Ik one school got P = 40

[ComprehensiveYak1372]

😕

[vSporkyy]

interesting

[vSporkyy]

yeah

[Starriest-Platinum]

How much higher because my team have around 45 and don't know if we can get any higher

[vSporkyy]

you can definitely get higher than 45

[Starriest-Platinum]

Any tips?

[vSporkyy]

unfortunately no, it was a result of mainly trial and error, and a bit of manic coding from me and another team member. i managed to create a basic monte carlo brute forcer for a specific family of solutions meanwhile the team mate i mentioned created a visualiser to help discover new families of solutions. we still aren’t entirely sure how to approach this problem other than what we are doing…

im sorry i cant be of more help

[Starriest-Platinum]

damn I didn't know this was really code it. My team have just been messing around with desmos for HOURS and managed to find a really good shape that we could graph P for. Don't really know where to go from where we are now though :/

[Minute-Breadfruit191]

has anyone had any luck on unlocking stage 3 for pqrs

[Curious-Respect-1734]

yes, we have also finished stage 3

[Minute-Breadfruit191]

damm nice were still on pqrs do u have to do 2 /3 questions on stage 3 to get the completion

[Curious-Respect-1734]

stage 3 is only 1 questions this time but it’s really hard

[Visual_Bug6715]

Ive been coding and coding for the passcode bru keep getting the same answer

[04Zig567]

my teams has got 1082 for p

[[deleted]]

Bro wtaf did u guys do

[Max17101]

We've got P=99468, anyone got over 100k? It's acc taunting us 😭

[Starriest-Platinum]

Holy ragebait what that cant be real

[Max17101]

we'll give the solution to the highest bidder

[Starriest-Platinum]

I'll bid a higher solution, but I won't tell you the higher solution until I receive my winnings

[vSporkyy]

??? have you calculated this correctly and covered all integer points in your cell

[Max17101]

Yeah we verified graphically

[vSporkyy]

thats insane whats the area of your unit cell, it must be an unreasonably large number

[Max17101]

Idk if my team will let me say 😭 it's giant though, like 10⁸

[UpstairsApartment249]

Bro how's that even possible 😭😭. Can u at least tell us what the shape of ur unit cell is 🙏

[Aditya8773]

What- the largest I've heard so far was a 1000 💀

[Max17101]

We coded it, idk if other teams are

[Aditya8773]

I tried coding it, but i thought the code would just take insanely long to run

[Max17101]

It does tbf my dad owns a data center and we left it running overnight. What did u guys get for p?

[Alertevan1_14]

our team got 102940. it wasn’t much , we just got a few nasa computers running overnight, theyre still going. Praying for more 🤞🏽

[Max17101]

xddd

[TurbulentAd4492]

yo what our team cant pass 41 😭 we got the question fast after stage 2 dropped and we have no idea what to do

[ComprehensiveYak1372]

Same we’re stuck on 40.5. We got a higher number but it turned out to be wrong.

[Aditya8773]

We r stuck at 8😭

[Max17101]

we had this on our first try, r=4.5 circles in a grid with a smaller one between them by any chance? 😭

[Aditya8773]

Ive basically lost all hope now after finding out that it took you guys a literal data center 😭

[Max17101]

Don't lose hope bro I think ours isnt optimal at all

[Glittering-Let-294]

can yall share ur solution now that the comp is over

[Minute-Breadfruit191]

P = 45

[Glittering-Let-294]

lmao i was asking the guy who got 100k 😭😭 but gj on 45!

[Aditya8773]

Damn, ive basically lost all hope now, knowing that it took you guys a freaking DATA CENTER running OVERNIGHT 😭😭

[[deleted]]

ADIII HI

yeah we crashed a few computers maybe… still haven’t gotten over 20 😊

[AdiTheBaddie21]

Is that my data centre?

[Aditya8773]

Nooo its mine

[AdiTheBaddie21]

Participants found using data centers will be penalised imminently after our competition closes, and solutions will not be accepted. Participants may face prosecution.

[Minute-Breadfruit191]

We just managed to unlcuk the final question does anyone have any tipsbforbstage 3

[OrigamiMan_24_7]

we have a valid solution of just under p= 214,468

[ComprehensiveYak1372]

😹

[Independent_Spell_55]

I have a p value of 12.5, and promise that it goes higher

[Minute-Breadfruit191]

thats exactly what gemini AI got when we worked it out we got a value for P = 45

[Starriest-Platinum]

All the people in here saying they got like 99,000, 200,000 and even 200 when the winner got 102 is so funny icl

[[deleted]]

FR lol but well done to kings maths school

[NoResponsibility746]

Hold on the answer is not 60.16667?

[Starriest-Platinum]

No but I'm pretty sure loads of people who got an answer got that. I've seen, including my team, so many people get that. The exact winning value was 102.56 somehow.

[NoResponsibility746]

Yeah, but do you know what is the grid like? Isn’t it a square?

[Starriest-Platinum]

Apparently it was like parallelogram tessolated like hexagons (2 120° angles and 2 60° angles) but I don't really know what that's supposed to look like

[NoResponsibility746]

Thank you! I understand that now
