Omnipwn Tournament: Dual Core

Re: Omnipwn Tournament: Dual Core

exactly.... but commander and I can't load the browser properly.... I have no access to a computer that has less lag than the one i'm on now... and this comp isn't even vista (single core ~1.6 gHz 512MB RAM...)

The best score I've gotten on browser was like high 400ks... there are 2 parts that I ALWAYS lag at... and get hit by the highspeed star (haha pun) that comes out.... because of the bad physics engine

can we issue a request for a no-background no-spazzy feature version? Not sure if it'll help much (the lag is mostly in the physics engine) but it will help a bit... and even a bit might help me avoid the star... which almost always launches like 3 of those big things at very high velocities randomly around the screen...

lol i'm so used to pressing E then Y now... xD

Re: Omnipwn Tournament: Dual Core

I guess I am ok right now since no one has beat my score, but if they do, I will be in trouble. I did not have the lag this morning.

Re: Omnipwn Tournament: Dual Core

Made mental 4 a bit easier. Asking for the white ball.

Re: Omnipwn Tournament: Dual Core

Alright mental 4 is much clearer now.

MrRubix, I would like to know how you are ranking the games.

The scores are different, and what if you got rank 1 on one game but like rank 10 on another? How would you be able to bring it together? What of the rank 10 on the other game was only 1 second behind the rank 1. So yeah it's quite hard to balance the two games out... UNLESS if you give 500 points max each game 1% off for each score less.... but apparently that's not waht you're doing. you're unifying the scores, and I want to ask how do you propose doing it?

Edit: ok the lag went away a bit when i closed everything (including firewall)... but still lagged like occasionally. I know I definitely can beat this score (assuming no lag)

anyhow, tass guess how I got good at this. Playing LOTS and LOTS of touhou... except thats keyboard, this is mouse, and this has a much larger hit radius and is much worse designed.

Edit 2: I expect score updates (your excel) will be up as soon as you have time? I'm not pushing you or anything...

Re: Omnipwn Tournament: Dual Core

so, do i get bonus points because i solved mental 4 before you made it easier?

Re: Omnipwn Tournament: Dual Core

this has got to be the worst round EVER... I can't do any of these... (but at least I play
reverse regularly xD)

Now time to whore fancy pants even more. I wanna make a vid for youtube xD

Who has mental 2 confirmed?

[MrRubix]

Re: Omnipwn Tournament: Dual Core

Tass: No, because going from one to the other is incredibly easy

Jon: The games are being cumulatively ranked. So if you get rank 1 on Velocity, you get 500 points. If you get rank 10 on the other, you get 500*(.99)^9 = 456 points there. In total for the round, you'd have 500+456 points out of a possible 1000

Re: Omnipwn Tournament: Dual Core

alright thanks rubix.

Edit: Mental 2 solved.

Re: Omnipwn Tournament: Dual Core

Rubix: then you should keep it at the initial question if it's so easy. .

Re: Omnipwn Tournament: Dual Core

A little help on Mental Round 4, because I don't want people to flounder, so I'll give a little help to get you all started.

Bayes Rule = P(A|B) = The probability of A happening, GIVEN that B has happened
Bayes Rule is defined as P(A|B) = P(A and B)/P(B)

Example problem: I have 52 cards and I draw a card. The suit is black. What's the chance of it being an ace?
P(Ace|Black suit) = P(Ace and Black suit)/P(Black suit)
We must evaluate the numerator and denominator as STANDALONE EVENTS.
Looking at *purely* P(Ace and Black suit) is simple -- how many black aces are there? Two. So that's 2/52.
Looking at *purely* P(Black suit) is simple too -- 1/2. Half the deck is black.
So P(Ace and Black suit)/P(Black suit) = (2/52)/(1/2) = 1/13

Also a useful rule to know. Say there are two vendors. One has a pickle and a burger, and the other has two pickles and three burgers. We pick a vendor at random and he gives us a random food item. What's P(we get a burger)? We can either get a burger from one vendor or the other. OR means we add probabilities. So P(we get a burger) = P(we get a burger from vendor 1) + P(we get a burger from vendor 2)

So for Challenge #4, you want the probability of drawing a white given that it comes from a certain box.
P(Ball coming from box 1 | Ball drawn is white)
P(Ball coming from box 2 | Ball drawn is white)
P(Ball coming from box 3 | Ball drawn is white)

The answer is obviously the one with the largest probability here.

Just because we know the ball drawn is white, we don't know which box it comes from.

Re: Omnipwn Tournament: Dual Core

oh bah. they could have easily gotten that from googling "bayes" and reading the wiki article.

definitely deserve bonus points after that. .

Re: Omnipwn Tournament: Dual Core

yeah. giving away such a hint is kinda stupid... it just makes the mental pointless.

[MrRubix]

Re: Omnipwn Tournament: Dual Core

Jon: Your answer's way off, so the hint may help you.

I think it's a necessary hint because nobody's actually solved it on their own yet except Fractal Monkey. Consider it a mercy hint, lol.

The mentals are only going to get harder -- I'm not going to be so nice in the future, lol. Next round, I'm going to give some teeth to these challenges >:] Take advantage while you can!

Re: Omnipwn Tournament: Dual Core

I have to say, I didn't see Bayes until my last year of high school, and NEVER saw/used it again until this year, with the subject Medical Statistics (I study medicine). Half of all the students present had never heard of Bayes in high school.

Btw Rubix, I thought you were going to upload the xls file with updated scores yesterday? Not trying to push you or anything though... Oh and here's my Music Catch score for round 3:



And the Velocity score for round 4:

Re: Omnipwn Tournament: Dual Core

WHat my answers way off? I guess my 5 minute readthrough of wiki's article wasn't enough. Tass got it wrong too. thats some assurance. Time to read up on bayes.. I haven't touched conditional probability at all... never knew it existed... and Stat got taken out of the gr 12 curriculum this year, so I'm kinda clueless.
