Some open problems in the world of ryzom that I am aware:

* "The craft formula": the holy grail of ryzom crafters. Given a database with all mats and its properties/stats, be able to figure the final stats of a crafted item knowing the pattern ant the number of mats and type it takes. The homin that figures this out... well...no words

* "The best overcraft formula": this one requires two assumptions, if we know the craft formula and the sucess probability given the overcraft delta (which are deterministic). The assumtions are a) knowing the random variable that models either a complete failure (no mats wasted) or a degrade in the event of a not perfect item and b) knowing the random variable that models the degraded quality knowing that it is a degrade (conditional probability)

Problem 1: compute the best overcraft delta that maximizes average (expectation) craft xp per crafted item (I'm not sure it's max delta)

Problem 2: assuming a crafted item can be sold for a price that depends linearly on the quality and the number of mats, compute the best overcraft delta that maximizes a linear combination of the average craft xp per item AND the economic benefit (thus problem 1 is a particular case of problem 2, or if xp is not important, the solution tells us how to get rich faster by overcrafting).


OMG... I'm a geek....don't mind me. I can't believe I posted this, now I'll go sit in the corner ... btw, who would pay for the answer to problems 1 and 2?

Those formulas are all pretty accurate, but last I tested, not 100% for all level differences. Ryzom seems to have strange ways of rounding it's numbers. So there's always room for improvement

Oh, and my C values for the herbies that were boosted in the recent patch are obviously outdated.

C value for steriod using herbies appears to be 6. (Oshido says so!)

-Raku

Well, if Saint Oshido (in his straight jacket) says so, then it must be so

I think I took notes during Madakam hunting just after the patch came out but never got around to analysing them, let me check. *opens closet door and is buried under enormous amounts of paper*

I believe we tested a ploderos and a madakam and they were 6.0. We haven't tested all of the updated herbivores, however so right now we're just assuming they're 6.0.

That's okay, I didn't test all of the nameds and bosses either before assuming they were respectively 8 and 25. I have enough faith in the consistency of the system to believe that if 5 nameds all have the same C value, then all nameds have the same C value, and thus all bosses have the same C value too. At least until I can prove otherwise

If I recall, before the patch madakam were 1.0 and ploderos were 1.5, so if they're both 6.0 now I think we can safely assume the bolobi and shalah are too.

since I digged that thread up again and the craftsystem changed I just did some calculations on that one
problem 1+2:
just craft at max ( Q = 50 above your lvl)
if the degraded items are equaly spread other the qualities or even when calculating with every degrade to be the minimum quality it comes to "higher = more XP"
in average u gain 122-146XP more per mat when crafting at max

for plain XP u should consider to just craft 50 above your lvl since the diggin would be faster for lower Q (so just dig mats 50 above the lvl you want to craft)
for money just take highes possible
