Overview

• reworked the SDL implementation and used a raylib one with lévy: → lévy flight is a mathematic pattern that imitates the hunting route from predators. Its using the power law distribution for getting the random jump $S$

$$ S = U-\frac{1}{\gamma} $$

Run

brew install raylib

git clone https://github.com/fivawyr/tiny_randomwalk.git
cd # where ever you clone this repo
╰─ g++ code.cpp -o randomwalk \
    -std=c++17 \
    -I/opt/homebrew/include \
    -L/opt/homebrew/lib \
    -lraylib
./walk
