🌟 About Evo

Evo is an advanced neural network-based evolutionary sandbox where AI agents evolve through natural selection.

Agents navigate an infinite 2D world, sense their environment using raycasting, and make decisions through neural networks that evolve over generations. Watch species emerge, compete for resources, and evolve complex behaviors in real-time!

🧬 How Evolution Works

graph LR
A[🌱 Birth] --> B[🏃 Life]

C -->|High| D[🔄 Reproduce]
C -->|Low| E[💀 Death]
D --> F[🧬 Crossover & Mutation]
F --> A
E --> G[📊 Selection]
G --> A

The Evolution Cycle

1. 🌱 Life Cycle - Agents consume food, expend energy, and age
2. 🔄 Reproduction - Fit agents reproduce through crossover and mutation
3. 📊 Natural Selection - Top performers survive, weak are eliminated
4. 🌈 Speciation - Species naturally emerge with unique colors
