Distribution Pipe Woes

[Bigglesworth]

So I have seven pulvs grind'n away, and in the back of them they are hooked to smelters via phased pipe brings them to my distribution pipes. I have gold pipes speeding things along.

In the first spread of distribution pipes I have it going three ways. Left, right and center(or forward). The forward/center goes to the center pulv. The left and right goto the three pulvs to the left/right of the center one. So green/left has a ratio of 3. Blue/right has a ratio of 3. And center/red has a ratio of 1. Left/right are then distributed evenly with a 1:1:1 ration to the three puls on either side of center.

Problem:
Center pulv gets 3x what it should be getting. Now as far as I can tell it has something to do with how many items are being sent though the pipes. In this case 3 items are sent from the smelters (from rich slag I get three ingots) so perhaps the stack of three counts as 1? But then wouldent that be irrelevant because the ratio would still come out to teh same when sent left/right? Is this a bug or am I doing something wrong?

The center pulverizer has a 1/3 chance to get it, all the others have a 1/6th of a chance.

You're putting them through 2 pipes, so that gives them 1/3 of the original 1/3 from the first pipe, whereas the middle one only has to go through one.

 

[slay_mithos]

It's just as lolpierandom said.

Basically, your first distribution pipe will split 1/3 to each of the 3 outputs.
Two of the outputs will then split again in 3.

But the one ine the center receives 1/3 of the first distribution pipe, and that is exactly 3 times what the others would get.

Your best bet is to have the same number of distribution pipes on each way, and an equal number of machines as an output.

Here, it would mean either to remove the center one (getting 2 lots of 3), or to add two and connect them so that each machine is connected to a distribution pipe that is also connected to a distribution pipe (3 lots of 3).

lolpierandom: Those numbers must be wrong, because 1/3 + 6*1/6 = 9/6 > 1.

Sorry, I don't know how distribution pipes work, but it sounds plausible, that your setup should deliver 1/7 per pulv.

No, each pipe is individual, and doesn't know if there are other down the line.

As for the numbers, it goes:

    9
    |
 d===d===d
/|\  |  /|\
1 1 1 3 1 1 1

9 being the input (9 items here for the example)
d the distribution pipes.
The numbers at the bottom the bottom being the result at the end of the route (in the machine).
So, yeah, the 6 is just a common mistake of 3+3 instead of 3x3.

I'm just wondering now, why he can set a ratio in those pipes (3 for left, 3 for right, 1 to the center), when these ratios are ignored according to your replies. If there would be no ratios and a simple round robin, the 3*1/9 + 3/9 + 3*1/9 would make sense. If those ratios would work according to intuition you'd get 3/7 to the left, 1/7 to the center, 3/7 to the right.

The center pulverizer has a 1/3 chance to get it, all the others have a 1/9th of a chance.

You're putting them through 2 pipes, so that gives them 1/3 of the original 1/3 from the first pipe, whereas the middle one only has to go through one.

FTFY

Derp, that was dumb of me, especially as I'm currently reviewing probability in Algebra 2...

 

[Bigglesworth]

This seems over-complicated. I have 1 set to the middle, and 3 set to the two sizes. I want 1 to go center and three to one side, and three to the other. Why is it not that simple? 2 sides get three (6) and 1 middle gets 1 for a total of 7.[DOUBLEPOST=1360145132][/DOUBLEPOST]

How does middle have a 1/3 chance when I have it split in a 3:1:3 ratio? Doesnt it mean 3left:1mid:3right ??? Lol why isnt this that simple.


What do I need to set these at to get even distribution? What is the flipp'n point of the ratio GUI if it doesn't function like it should?

 

[Bigglesworth]

Still wondering what I need to set the ratios to..

I'm sorry for bumping the topic, but I'm tired of searching in google for a distribution pipe updated to 1.4.7 (as you can see this is what I found) since I really want it for my world, could you please post a link to the topic or a download link? I will appreciate it.

I'm using that mod in Ultimate and it seems to work fine.

On topic: You can see how the pipe works by throwing in items, if it's not distributing properly I can only guess something isn't working as it should... If you set it to 3:1:3, but it does 1:1:1 then obviously it isn't a mistake on your end.
I honestly think this is a case of just throwing in some items and watching what happens.

btw, the iron pipes will mess up the distribution if the distribution pipes sent anything that way. You should set the distribution pipes so they can't send anything back where it came from. If you already did that then ignore this comment, the point is you shouldn't need iron pipes to prevent items from being sent back in this setup as they'll mess up the distribution (items will basically get counted multiple times and can mess up the "rotation" of the distribution pipes).

YES! thanks! now at least I can set up my compact biomass farm without using a crapload of relays or even redpower itself.

Oh, and no worries, I do know how to use the pipe already, used it a lot back in 1.2

The "on topic:" bit was for Bigglesworth, though I'm hoping he found a solution by now.

 

[Bigglesworth]

I would suggest using pneumatic pipes, as distribution pipes logic is, to be frank, retarded. Unless they updated them to not be full of durp. https://github.com/tcooc/AdditionalPipesBC

Beat to it. man, these forums should dynamically update with new posts!

 

[Dravarden]

Pneumatic tubes fill up the first inventory then go to the second, unless you do stupid shit with relays and a square... and I like more buildcraft pipes.

 

[Bigglesworth]

yeah, if you like leaky pipes. My pneumatic tubes distribute evenly just fine, you just have to use your head a little.

appart from the head, resources...

anyway, I like my good ol' pipes with gates, NBT data, and compatible with every mod.

 

[Bigglesworth]

I still use BC pipes and gates, I simply use pnumatic tubes as well. Why limit myself when I know the pros and cons of both. But whatever floats your boat---wait, you use only BC pipes, so i guess your 'boat' would not float long

 

[Dravarden]

Who said I don't use them? I use them for sorting quarrys, not for distributhing, something they can't do.
