Creavita

Creavita is a simulator of natural selection. Cells on the field have their own genomes, which can change when a cell is reproducing.

The Genome Structure

The genome is a string that encoding the behavior program of the cell. It consists of 3 letters: "A", "C" and "D".  The first 12 symbols are reserved for a "philosequence" that defines the "attraction force"  of the cell to 6 stimuli that include:

• light-mineral (top-bottom) direction
• horizontal direction (*)
• corpses
• "Carnivores"
• "Algae"
• "Mineral Eaters"

Duplet	Value	Duplet	Value	Duplet	Value
AA	+4	CA	+1	DA	-2
AC	+3	CC	0	DC	-3
AD	+2	CD	-1	DD	Random

(*) Horizontal direction is always randomly choosed. The force varies from 0 to 3,5.

The rest of the genome is divided into "proteins" that perform various functions (You can see them in the table).  Reading of the gene spends energy. If the energy reach 0, a cell turns into a corpse.

"Protein"	Coding Sequence	Function
Duplicase (D)	CDA	Divide
Movease (M)	CAA	Rotate according to the philosequence and move in this direction
Photosynthetase (P)	CCC	Get energy from light
Organase (O)	CCA	Get energy by eating other cells
Mineralase (N)	CCD	Get energy from minerals
Storagin (S)	CDC	Increase cell's energy capacity
Musculin (U)	CAC	Increase cell's speed
Cytoskeletin (K)	CDD	Increase cell's health

S, U and K are so-called "characteristic genes" and since the genome is looped, their effectiveness decreases  with each cycle. After reproduction, it recovers.

The main genome also contains conditional blocks that allows execute the next gene only if the condition is fulfilled. Currently, only 1 condition is available:

AA__ - energy >= x * max energy capacity

DA__ - energy < x * max energy capacity

Duplet	Value of x	Duplet	Value of x	Duplet	Value of x
AA	90%	CA	60%	DA	30%
AC	80%	CC	50%	DC	20%
AD	70%	CD	40%	DD	10%

Besides, there is connection block [DCC] that extends previous conditions to the next gene.

World settings

The second mutation can occur if the first one has occurred, the third mutation if the second one has occurred, and so on.

You can drag endpoints of energy graphs.

Enable apoptosis means kill the cells without duplicase.
