👋 Hi, I'm Serhii — aka xcont

I'm a self-taught developer working at the intersection of optimization, pattern formation, and cellular automata.
I build experimental systems where complexity emerges from simple rules — using code, recursion, and a bit of imagination.

Genetic algorithm that evolves cellular automaton rules to maximize specific behavior (like flickering, stability, or growth).

A genetic algorithm evolves the initial field state of a cellular automaton while keeping the rules fixed.
The goal: observe what kinds of behavior or structures can emerge from a Turing-complete substrate.
It’s a search for dynamics, complexity, or stability — without touching the rules themselves.

Fractal patterns generated via recursive substitution, then evolved using a genetic algorithm.
Focus: visual symmetry, self-similarity, and how simple logic creates structured complexity.

Fractals from a single point — grown using either cellular automata or convolution kernels. This project explores 6 minimal systems that all follow the same basic idea: Start with a tiny seed, apply a deterministic transformation, pad or copy, repeat. Fractals emerge.

But here’s the twist — CNNs (convolutional neural nets) do the same. They copy, convolve, repeat. So what happens when we apply the same kernel over each iteration? You get... fractals. Turns out, when a neural net "draws a cat", it draws a fractal that looks like a cat.

→ fractogenesis

Fractals generated by recursively permuting pixel arrays via a quadrant-based shuffle operation.
This deterministic process reveals deep structural symmetries in both binary and full-color images.

The method echoes spatial structure-modification routines found in convolutional architectures (e.g., padding and upsampling),
though it diverges from convolution by applying no local aggregation — only recursive, deterministic reordering.

Complexity isn't magic — it's just logic repeated until it surprises you.
