evolution-simulation

This program simulates emergence and natural selection in biological systems using a few basic components.

Sample execution

Organism Mechanics

Organisms are represented with nodes in a graph, each color representing a specific node element. Each line represents a bidirectional connection in the graph organism.

An organism!

Each node has an energy property (represented by brightness) that must be kept above zero to prevent the organism from starving. This can be achieved through consuming food particles or predation. Nodes lose energy over time and viruses can deplete energy more quickly.

Food producers and particles

Virus producers and particles

Organisms have "DNA" which is represented through code containing lines of nodes to create and which nodes to connect to. You can create your own organisms through the program's code editor. As the organism gains energy, it will read through its code and add nodes with their respective connections. If an organism has enough energy, it can duplicate its reproductive node and code which will then grow into fully a developed organism.

Node Table

Tag	Col	Description
nod		Structural, strong virus resistance
eat		Consume food for energy, low resistance
run		Moves away from other organisms
jit		Jitter randomly
rot		Rotate randomly
fol		Moves towards other organisms
pre		Siphon energy from other organisms
sto		Radius changes with energy, high max energy
gat		Moves towards food circles
rep		(cannot be coded) Organizes growing and replication

Example Code

eat 0
rot 0

Also, multiple node connections can be made in one line.

jit 1
rot 2
rot 2
nod 3
nod 3 5
nod 3 6
nod 4
nod 4 8
nod 4 9

Evolution

When an organism duplicates, its code can contain errors through swaps, deletions, and insertions. Over time, many organism types can be created.

Evolution

Experiment with the starting conditions to see what organisms you can create!

Running the program

The release files were compiled using Java 17. If you encounter errors while trying to execute the jar, ensure that Java 17 is configured in your PATH and run the program from the terminal.
