Artificial life simulator

Evosim is an experimental model of an artificial genepool. The main idea is to simulate co-evolution where creatures are competing for food and mates simultaneously and directly.

The idea for this project came to me when I started finding similar projects that caught my attention and reading what others say that they want to see: interactive artificial life.

This project doesn't have any interactive elements currently, since it's a prototype of the core elements of the simulation, however this is an aspect that I intend to explore in the future.

The simulation starts with a number of randomly generated creatures who evolve through the process of natural selection, thereby becoming more able swimmers and making it easier for them to find food and find mates.

Every feature of a creature is determined by its genetic model: a container of attributes that decide its size, colour, limb structure, and movement pattern. All of these attributes are subject to change via mutation and crossover when creatures produce offspring.

In this prototype I am currently able to run a simulation of approximately 200 creatures which is far more than I expected when I started; I would have considered myself lucky to be able to have 50.

I used Unity for this prototype because it made it easy to start the project and see results quickly. I am very happy with the results and would like to take this further in the future.

I would also like to remake this project more fully using the Bullet physics engine which, from what I understand, is more suitable for this application than the physics engine that Unity uses - PhysX.
