Re: Compost Bin Purity: Oh crap, how do earthworms work?

[Erunildo]

So i made some experiments and came up with a formula which can calculate the result of 1 of the elements of the humus based on the elements of one python. I am waiting for some more humus to see if i can adjust it for more than 1 pythons. Also waiting on humus to calculate the same formula for worms.

I managed to predict the outcome of the element of the humus so i guess this must be working. If someone could find a way to combine all these together,i would really help.

Formula:

H(element)=W(element)*0.077 + Bin(element)*0.924

With
H for humus
W for worm

The values must be of the same element.
For example
H(merc)=42.27*0.077 + 25*0.924
H(merc)=26.35

There is a small margin of error,i used up to 3 decimal numbers.

Conclusion:

If this is correct it would seem that the purity of the bin is what really matters.

Two reminders to formula-crafters:
-If the constants you use in your formulas are not whole numbers, then the formula is probably wrong. Nobody would write code with "0.7592" as a deliberately used constant.
-The contribution of earthworms/pythons is likely a Weighted Average of Variable Weight. That's the key: the weight changes with purity. This means you cannot create a formula based off of a single Worm/Humus pairing.

Nobody would write code with "0.7592" as a deliberately used constant.

Damn... better change my code, then. This game I've been working on has all sorts of fractions of Pi.

Known fact that the devs like working with irrational numbers, so take this into account.

You guys are amazing!
I am still waiting for my 1st gen lead tree (planning to find out what I can get for 2nd Gen)
hopefully I could come up with something later!

Keep up the good work : )

First,thanks for the comment.

As for the 0.75 i also doubt they used it as a number,i am guessing they have a universal formula that makes the calculations. Although, if what i did is correct (even for 1 worm),it would mean that even high purity worms won't do you any good without a pure bin,so basically it's useless to farm worms (if you raise the purity of the bin,you will also raise the purity of the worms that come out of the bin). So feeding worms is useful only in changing the elemental composition of the worm. Anyway,i made an attempt at the formula mainly because i was too lazy to work on my trees purity:P

As for your second point,i was hoping you could somehow use what works for 1 worm and extend it to multiple worms. Since this is not the case and my math has it's limits,i will leave the formula to the pros:D

Thanks

P.s Or the devs could take us out of our misery and gives us at least an idea of what is going on. Just saying:P

This thread makes my head hurt.
I came to play a game..., sheesh...

For lack of an actual formula, I'll just point out the conclusions we've reached so far, so that we can at least guesstimate some outcomes. It seems that the higher the purity difference between the bin and the worms, the less weight the higher purity element will have. So ideally keep the difference in purity moderate, but not too moderate. Ideally we'd be able to find the sweet spot where reducing |bin_multiplier - worm_multiplier| would cause the purity to go down, and increasing the same difference in purity multiplier would also cause the resulting purity to go down. Worm efficiency might also play a part to some extent, and I'm just going to assume that higher purity gives more weight to the worm mix.

[Burseig]

so basically it's useless to farm worms (if you raise the purity of the bin,you will also raise the purity of the worms that come out of the bin).

Sorry but new worm comes with 25.0/25.0/25.0/25.0 so you have to farm the worms aswell
And what I noticed is that new neutral worms don't lower or affect humus alchemy.


Regarding Worm efficiency, I have a theory.
Worms impact the alchemy of humus regarding their alchemy values. More worms will impact more. But if you are at 100% efficiency, adding more worms will not help. So only the worm that build the efficiency up to 100% are taken in account.
Someone rich in python can test.
Compare 7 pythons 112% capped at 100% and 8 pythons. Will you see a difference in the humus alchemy?

[Burseig]

Formula:

H(element)=W(element)*0.077 + Bin(element)*0.924

With
H for humus
W for worm

With how many examples did you test your formula?

I made a bin lead 25.44. I got humus lead 25.13 without worm. Adding a 25.0 worm will not change anything. (your formula predict a 25.43 humus).

[lachlaan]

Someone a few pages back already reported that a worm created by the bin, while he already had 100% efficiency in the bin, actually raised the humus purity by a bit. So its elemental composition did count towards the final result despite it being over the 100% efficiency.
