Introduction

After some attempts it seems that vine cuttings crossbreeding is not as 'chaotic' as it could be. There are a lot of data for each cutting but they often share a lot with other cuttings.

The goal of vine cuttings crossbreeding is of course to produce one that is good on every attribute, but better short-term goals should be chosen. Certainly a good grapes/quality/sugar cutting would be great.

Coordination

Many things can be done to help. We need:

Basic cuttings attributes

There are 7 primary attributes associated with vineyards that are changed each time a vineyard is tended. From an analysis of all the tending data for all of the basic cuttings (those from universities), one can note that there are a lot of simularities shared between vines for each attribute. In fact, If we look at each of the seven attributes independently, we can assign a specific 'data-set' for that attribute on a specific vine.

For example, If we were to say that Distinction and Appreaciation both use data-set A for the Acid attribute, then we can expect that the way acid is effect for each tending method of each tending state will be exactly the same for both vine types.

The following table shows all of the basic cuttings, and the data-set assigned to each attribute:
Cutting Acid Color Grapes Quality Skin Sugar Vitality
Distraction A A B A A A A
Contemplation A A A D C A A
Appreciation A A A C A A A
Balance B B A B B B A
Wisdom A A A A D A A
Amusement A A B A A A B
Frivolity C C A A A C A

Is there any reason why we're using this arbitrary notation here rather than something corresponding to actual mutations on the vines? --Shelyak

This next table shows the average of each data-set for each attribute. The higher the average of the data-set, the higher overall values that can be expected for that attribute using a given vine cutting. For example, for grapes, the average for data-set A is 25, and the average for data-set B is 73. Thus, one could expect to get about 3x more grapes using a vine that has a Grapes attribute data-set of B than you would using a vine that used set A.

Data-Set Acid Color Grapes Quality Skin Sugar Vitality
A 16 37 25 34 43 23 -393
B 34 3 73 36 46 75 -287
C 93 177 4* 28 23 9 --
D -- -- -- 18 128 -- --

Hybrid cutting attributes

This section contains data-set information that is associated with some of the hybrid vine cuttings that were created via the crossbreeding skill. You should use the same average stats table from the section above to get the data-set average for each given data-set.

See above note. This A-D notation should be replaced with the more logical and consistent mutation count notation. See Vine Genetics and the Phenotype Table. --Shelyak

Here is the prvious table that was here that does not contain any of the data-sets for the vine types. As the various crossbreeders provide there attribute information, they can be removed from this table:

Left Right New cutting Description
Distraction Appreciation Eigam60 basic everywhere except Grapes and Qualities that have new columns
Appreciation Distraction Eigam61 Exactly Distraction
Balance Distraction Eigam62 Distraction with Balance's sugar column (so grapes + sugar, interesting)
Distraction Balance Eigam63 Distraction with Balance's grapes,quality and sugar column
Appreciation Distraction Eigam64 basic everywhere except Grapes and Qualities that have new columns
Distraction Appreciation Eigam65 Exactly Distraction
Balance Appreciation Eigam66 Appreciation with Balance sugar column (quality+sugar)
Balance Appreciation Eigam67 Exactly Appreciation
Eigam62 Eigam64 Eigam71 new Quality, new Grapes, Balance's sugar

Generalities on crossbreeding

This does not means to be complete, I put that here as basic information on how crossbreeding could work. Should be writtend again by someone knowing crossbreeding better than me.

This is not how vine cutting works, this how it may work.

We speak about genomes, which are sequences of letters, of a fixed size. The letters are taken in a set of, for example, 4 letters, {A,B,C ,D}. If the size is 14, a genome can be AABDBCDCBAADBA. This contains all the information about a specific cuttings. This information can be encode in many different ways. Just 2 basic examples:

When you crossbreed by placing 2 genomes, one on the left and one on the right, a position in the sequence is randomly chosen. Both genomes are cut at this position. And the left part of the left genome is mixed with the right part of the right genome. For instance left = AABDBCDCBAADBA and right = BBDBACCDCADBAA, cutting on the 5th letter produce the genome AABDB.CCDCADBAA = AABDBCCDCADBAA

Mutations may happen, changing one random letter in another one.

Please note that many variations exist. The genome can be directly a sequence of integer values (for example a random seed and a amplitude), or anything else. This is just a brief description of the basic idea of genome crossbreeding.

Theories

From the first few data collected, we can already see some interesting facts:

An hypothesis is that sugar is encoded in the left part of the genome. Quality and grapes may also be encoded more on left than the other, but at the right of sugar. Quality and grapes may be linked together, or mutations appeared.

This is not a lot of theory but perhaps it will help :)
