DSIM means "darwin_sim".
DSIM is a small Linux project under GPL. DSIM tries to simulate the Darwin theory, by by generating entities, having some characteristics.
Those entities belongs to one of the 6 species of the program.
Each species has some properties about reproduction, sociability, etc ...
This properties will make the species to evoluate, progress or disapear.

The characteristics:

Here is the list of characteristics supported by darwin_sim beta2:
_ species (6 different species: "Feulu" ","Milov ","Kapos ","Makas ","Plito ","Chimere")
_ name
_ sex (male, female, unknown (for chimeres), pregnant)
_ gestation (depending on the species)
_ age (time life depending on the species)
_ chief (who is the master of the colony, if the entity has accepted his authority)
_ rank (under the authority of a master ?)
_ sociability (depending on the species and the mother's sociability)
_ position (where's this guy ??)

The rules:

Only two rules are actually supported: reproduction and social life.

The reproduction

Two entities can reproduce, if they are in the same place... ;)
They also have to be from two different sex, and the female must not already be pregnant.
If they comes from different species, the PRC_RTD variable, specifies the inter-species reproduction rate.
(generally low...)
This type of reproduction will create a new entity of the chimere species, unable to reproduce, and very agressive.
If they are from the same species, the rule refers to the intra-reprodution rate.
The reproduction will create a new entity of the species.
If his mother was in a colony, she was quite sociable, and being born in a colony, he will be more sociable than his mother.

The social life

Depending on the sociability of each entity, some of them can decide to form groups.
A male leader is elected, and becomes the master of the colony.
