Protect my tribe: result

Here is a screen capture of the Creature geographical distribution after some iterations of the simulation:

We see that each Specie occupies a closed portion of the world, and there is some kind of no mans land in-between each Specie. Why? The explanation is quite simple: for a member of your own Specie to reproduce safely, you need to keep the other Species away, i.e. Kill them. The width of the no mans land correspond to the range of the Kill Action: 2 Grounds. After quite a number of generations, this behaviour emerges within the population:

Interpretation of the Behaviour:

• The first rule says: if my Energy is low, I look for some Food.
• The second rule says: if I find a Creature that is Alive, of different Specie and Moving, I kill it.
• The third rule is actually useless because the Speed cannot actually reach more than 1.
• In summary: if there is a Creature of another Specie around, I kill it. If not but my Energy is low I look for nearby Food, otherwise I perform the Default Behaviour.

This behaviour appears after quite a long time of simulation. Here is the simulation graph:

We see that the number of Creatures is decreasing, meaning that the emerging behaviour is not optimum for the overall population. However it is a better behaviour to protect your own Specie. In other words, it is possible through artificial simulation to have a group self defense behaviour to emerge, even when this is detrimental to the overall simulated population (the overall population is decreasing).

Conclusion

Any conclusion of these tests?

• First: don't play with Energy conservation. If there is a way for the Creatures to globally increase their population by multiplying the available Energy, soon or later the Creatures will find it (through evolution obviously).
• But most interestingly those simulations show that Creatures can develop (through evolution) a non selfish behaviour, a behaviour that is beneficial to a group of Creatures. Such behaviour exists in nature, like the warrior ants. And these experiments just show that it can also emerge from an artificial simulation.
