# Lorenz attractor on Golem network

![gif animation](./output.gif?raw=true)    

The Lorenz Equations are a system of three coupled, first-order, nonlinear differential equations which describe the trajectory of a particle through time. The system was originally derived by Lorenz as a model of atmospheric convection, but the deceptive simplicity of the equations have made them an often-used example in fields beyond atmospheric physics [[1]](#refs).

```bash

$ sudo apt-get install ffmpeg

```

### Install python requirements

```sh

$ # Using python3.6+

$ source ~/your/virtual/env

$ pip install -r requirements.txt

```

### Build using docker

```sh

$ docker build -t golem-lorenza:latest

```

### Build/push Golem vm

```sh

$ gvmkit-build golem-lorenz:latest

$ gvmkit-build golem-lorenz:latest --push
