I hate Wharton.

Hehe...the lazy answer would be, "When x is equal to 0," but I'm assuming your question has an implied system domain of x>1.

P.S. - Actually solved a little while after my "onozimlate" post, but not going to actually complete due to not wanting to feel obligated to rack up more points...XD

[MrRubix]

LOL it makes no sense to have a "negative component" system.

I think I got it right but holy crap was it hard to solve.

lightshark: The rounds are all open, so you may as well submit what you've accomplished. You may feel an urge later to give something else a try.

[lightshark]

Nah...I'll just bask carelessly in my indifference. :/

That's why I said it's the lazy answer. XD

Da key is da 1/2 functional requiyament! Just do a barrel roll!

Ok, ongaku sucks and rainbow blitz sucks even more >

[MrRubix]

lightshark: Do you mean solving riddle 5 or the whole riddle?

[MrRubix]

I think you guys will enjoy tomorrow's challenge.

[lightshark]

I meant the whole riddle, except it's still in raw form on mah notepad.

I'm really just here for the brain exercise, not for the competition. : O

When is the next mental challenge?

You should make it an interdependent series of quantitative finance systems.

Or maybe not...

[mike2727]

I hope the mental challenge involes intergers rofl.

[MrRubix]

The next mental challenge will be much more straightforward without any "tricky" riddles. I have not fully designed it yet but I have a feeling it will involve a series of flash games and other sorts of puzzles. If I do include tricky riddles, they will be Bonuses.

[Mitchtyler]

Nice. No ongaku please!

Cool. I still haven't figured out any of the riddles for this round. Oh yeah and umm, for one of them, the diamond one, how do you make it a picture again after you've changed to coding?

[Mitchtyler]

Do you only get credit for 3rd round if you complete all of the challenges?

[mike2727]

Do you get any credit if you finished part of Ongaku?

[MrRubix]

No, for Ongaku you must complete the goals for full credit.

As for the challenge round, the goal is also to solve the entire challenge. Since the tournament is always open, odds are, with enough help, you'll get it solved. Just do it quickly enough before others do, lol.

[mike2727]

Fine. I'll try ongaku again.

[Tasselfoot]

i could solve your wharton probability question.... seems like a pretty standard type question from the actuarial sciences 1st exam.

[MrRubix]

Would love to see your solution I ended up getting a critical point of 1/2 for the probability proof


More stat tomorrow, OPIM wednesday, two finance midterms on Thursday... gah.

[Tasselfoot]

i'm WAY too lazy to actually solve it. just saying that i likely could.... although it's quite possible that i'm missing something in the complexity of the issue, because at first reading, it doesn't seem to be THAT complex of a question.

[MrRubix]

It's saying, at what critical value of p does a 2k+1 system have a higher probability of working (ie. more than half its parts working) than a 2k-1 system given that a part works with probability p?

IMO it's pretty complex when you start digging into the combinatorics and transformations. Then again I tend to suck at stat.

[MrRubix]

Decided to add Round 4 in case I didn't wake up tomorrow morning early enough lol.


Enjoy, everyone!
