That's correct but mmmm if u count Zvt = TvZ it's more likely to happen

Oh man by continuing this conversation even further you're making me want to find large stockpiles of bricks.

Jesus Christ, calm down people. If what Testie said is true, which I do personally believe, Blizzard obviously implemented bias in the randomization algorithm to prevent morons complaining "omg random is fucked up cuz we all terran!!!!!! gayyyyyyy" Apparently, they wanted it to be an even distribution of races when random is selected by more than one person.
All in all, who gives a shit. We could all use some variety.

t-33% p-33% z-33% where does that other percent go?

yeah sometimes it feels like its not completely random when you get the same race several times in a row.. but on avg i think its been pretty random for me in the long run
Although i do find the random race assignments testie mentioned quite interesting.

calm down, from what?
Testie's the one throwing a tantrum that only Elton John can appreciate. But if you like suckin' Testie's nuts (pun fully intended) then so be it.

random ISNT random tho, at least not in random vs random.
it's built in to decrease the chances that you get the same race for both players.
had it been let alone it would of course be 1/3 that u get either zvz,tvt or pvp (since no matter what the first player gets, 1 of the 3 races drawn by player2 would mena they got the same one).
however, I believe blizzard edited this so that it would only occur 1 in 27 times!

I think Testie is right on the random thing...although it does puzzle me as to how you can actually get a mirror match, then, if it always 3-3-2, 2-1-1, 1-1-0... Can't anyone remember having played something like rP-rZ versus rP-rZ ??
About the thing being random for a single player, it uses the system clock. I now and then play vs racine, and if i mess up my split i restart. You get 1 race for about 30secs-1min, then the next, then the next again. Try out plz? I think they're just using a few bits out of the system time. Kinda silly, but who restarts the game that often anyway? I don't think the regular 10 games-in-a-row of one race is non-random, or influenced by previous games, but i am not 100% certain here.
And plz stop talking about the coins, the probability you get the same matchup vs some other dude 3 times is: 1 (you,any race) x 1 (him,any race) x 1/3 (you2) x 1/3 (him2) x 1/3 (you3) x 1/3 (him3) = 1/81 The chance of you and him getting a particular matchup (like t-z) 3 times is : 1/3 ^ 6 = 1/729 (replace the 1's in the previous example by 1/3)
just like the probability you get heads 3 times is 1/8.
edit: t: z without the space results in some stupid smiley

the first post that mentioned actual chances was
me and my friend had zvt in rvr 3 times in a row
i believe thats 1/729 chance
the whole point of random is anything may happen, its designed to have equal odds but you could have same race for 8 games i suppose(more chance than most lottery :o)
He didn't say. "Damn, we had zvt times in a row, it was a 1/729 chance to get it again!". he said "damn, the chances of getting zvt 3 times in a row are 1/729".
The only part of that should be in debate is whether TvZ and ZvT are the same thing. (and they aren't if he specifically got only zerg or only terran in all 3 games).

btw, can't we mail bliz asking how the random system works? they should be friendly enough to tell us..
|
I have disassembled Starcrafts "random" algorithm long ago, Nal_testie is right of course. It's quite complex and the person who coded it was probably drunk. The probability of a mirror 1vs1 matchup if both players go random is exactly 1/24, for instance.

For how fair this game is i think blizzard would have taken the extra 5 mins to make it random :D

This is too much math to think about over christmas break :D.

Isn't it all just a series
If true then excute this
Else

There are LOTS (infinitely many, in fact) of mathematical functions that generate sequences of random numbers. E.g. set your calculator to Radians mode (as opposed to Degrees mode) and enter any number other than 0 into this function, in place of x:
f(x) = sin (4 * x)
Now take the result ("f(x)") and enter it into the function again, in place of x. Do this over and over and you'll get a random sequence of numbers between 0 and 1.
Of course, the functions used in real random number generators are much more complex. With this function here, if you get a number that's REALLY close to 0, then the next number will also be really close to 0, but slightly farther away. A proper random number generator should not be this predictable. Furthermore, this function does not result in uniformly-distributed numbers, i.e. you are more likely to get some numbers than others. A proper random number generator should return uniformly-distributed numbers. And yes, such functions do exist.
For more information or examples, use Google .
Oh, and last of all, computers usually generate the initial value based on the computer's internal clock, e.g. they might use the number of milliseconds that have elapsed since midnight and generate a sequence of random numbers starting from that value. Alternatively, the computer can use a given value, and this is what SC will do when you play a replay: it will start with the same value that the actual game started with. This will result in the exact same sequence of random numbers, allowing the game to be played back correctly.

Oh Bill, you sound so sexy when you try to confuse me with big words.

dunno about anyone else, but when i random, i get terran mostly, then zerg, not much protoss.
somedays i can get protoss like 3 times in a row, but then it will switch back to terran.
the random thing can mean random, but in the 7 years ive played, random is terran favored.

i remember back in tha days 1.6 when we both go random i could guess ppl race by there color..On Lost Temple Ladder
Maybe im a magician..

IF 8 players random there will be 3/3/2 If 4 players random there will be 2/1/1
IT WILL NEVER EVER EVER BE DIFFERENT
Stop pissing me off.
do you have proof?
if it's unlikely that the 2 random players in a 1:1 have the same race, and we have similar effects for games with more than 2 players, then, it makes no sense to me for this to be programmed specifically for certain ammount of players in a game, but instead an effect of a general algorithm.
my point is, it makes no sense for it to be impossible to get more than 4 players of the same race in an 8 player game (with all random players, yes..)
also, i am quite certain i have been in a 6 player racewar game where there were 4 of one race (everyone left the game ofcourse). that was one game of several hundered, however, since some games end early because of lag or other problems, this would not be valid statistics in any way, however, they do show the existence of the possibility of 4 of one race in a 6player game, unless i'm insane and imagined it :-/.
