Ng Voting Algorithm [math]!!

[DarkFireball]

Hey guys, Darkfireball here.

Today we're going to talk about the Newgrounds Voting Algorithm to confirm which is correct.

Originally I assumed that the voting worked like this:

Small numbers for simplicity
5 voters0, all have voting power 1.0, 4 vote 2, 1 votes 5.

(2x1.0)+(2x1.0)+(2x1.0)+(2x1.0)+(5x1.0) = 13votepoints / 5total votes = 2.6.
Which to the average person would seem correct.

Now lets give one of the voters that voted 2 a voting power of 3.2.
5 voters, 1 votes 5 with voting power 1.0, 3 vote 2 with voting power 1.0, 1 votes 2 with voting power of 3.2

(2x1.0)+(2x1.0)+(2x1.0)+(2x3.2)+(5x1.0) = 17.4votepoints / 5 total votes = 3.48

Lets assess what happened. Math allows us to reverse the multiplication process, meaning a vote of 2 with a voting power of 3.2 can also be seen as a vote of 3.2 with a voting power of 2.0. This made the score of the submission rise, when a stronger 2 should have lowered the score.

Now, this looks wrong, but notice how we re-did the INITIAL score of the video.

Lets do this again, but working off of what we have.
(2x1.0)+(2x1.0)+(2x1.0)+(2x3.2)+(5x1.0) = 17.4votepoints / 5 total votes = 3.48 is the established score. 3.48.

1 New voter: voting power 1.0, votes 4. We should see the score rise slightly.
17.4 votepoints + (4x1.0) = 21.4 votepoints / 6 = 3.56. Hey what do you know. This looks correct, but it isn't.
========================================
========================================
=============
A vote on Newgrounds.com is not worth VOTEPOINTS, but actual Votes. The actual number of votes must increase.
========================================
========================================
=============
Lets do this. 3 people, one votes 1 worth 2 votes. one votes 3 worth 4.2 votes. one votes 5 worth 2.8 votes.
Newgrounds, by my assumption, must use 2 vote variables per submission. One for calculation, one to show how many users voted.
(1x2.0)+(3x4.2)+(5x2.8)= 2+12.6+14 = 28.6 totalvotepoints / 9 totalvotes(by WEIGHT only) = 3.17777. This would show only 3 votes on the submission page.

Lets build on this and confirm it. I come along, with a voting power of 4.9. I vote 5.

28.6 totalvotepoints+(5x4.9) = 53.1 totalvotepoints / 13.9 totalvotes(by WEIGHT only) = 3.820. This would show only 4 votes on the submission oage.

And We have a winner!
[( votepoints x voteworth ) / voteworth]

I was bored. Thanks for reading and hopefully this was informative.

Eww...do not bring school to NG...

Pretty impressive that you actually sat down and did the math.

I'm not impressed at the level of mathematics, just that you had enough time to do that.

[satanbrain]

that's why i always vote 0

Oh fuck this. While I read it and kind of understood, I still have three days before school, so leave me alone.

Why the hell didnt my strong work??

I think I was ending with instead of no /.

Damnit.

TL; DR for those who are too lazy to understand: the higher your voting power is, the larger of an impact you have on the score of that submission.

LOL YOU DUMBASS

you fail at math

heres where you went wrong:

"Lets do this again, but working off of what we have.
(2x1.0)+(2x1.0)+(2x1.0)+(2x3.2)+(5x1.0) = 17.4votepoints / 5 total votes = 3.48 is the established score. 3.48"

you dont divide by 5 votes
since one guy had a voting power of 3.2, he counts as 3.2 votes, not one.

So its actually 17.4/2.4 = 2.41
which is correct
and reasonable
and how it actually works...

[W0oJ0o]

sorry i meant * 17.4/7.2=2.41667

Tell me something I don't know!

[W0oJ0o]

O i am sorry, i should have read your whole post lol
my bad

[DarkFireball]

Lol w0oj0o... I was about 5 seconds from telling you to read the whole post about LEARNING how it works, showing an example, and then showing its wrong.

You earned my respect by replying again tho, thanks man.

So that whole post was explaining what everyone already knew

A voting power of 5 is like voting 5 times with that score, etc.

[Mz-frost95-fr]

Yes there are many many ways.

Actually, his 1 vote has the value of 3.2 people. So really, you're the one that fails.
