Laravel 7.x — P3 : First Route
The primary job of any framework is to process requests. It’s important to know that the user will attempt to retrieve a page from your site, or submit a data to your site. What happens when the request enters the Laravel framework? How is Laravel able to retrieve the content that the user wants and return it to the user? This is a topic that’s beyond the scope of this article.
What we want to know is when a user requests for a specific page, like the about page, how can we provide him/her with the about page content consistently?
Before we create our first route, we should be aware that Laravel is an MVC framework. Don’t overthink this term; it just stands for Model-View-Controller. Think of the _model _as your database table. The _view _is the HTML/CSS (and even JavaScript) content that’s given back to the user. If you are looking at the page, that’s the view. Laravel returned the HTML to your browser and your browser was able to translate the script into a visual representation of the HTML/CSS code. The _controller _is what communicates with the _model _and the view. It first receives the request from the user. If any data is stored in the database, the _controller _tells the _model _to retrieve the data. The model returns the data to the controller and the _controller _passes the data to the view. Once the _view _is generated, the _controller _returns the _view _to the user.
But how does the _controller _get called in the first place? If we can have hundreds of controllers, how does Laravel know which _controller _to call? By looking at the routes that are specified in the routes file (routes/web.php).

CellularAutomata.jl: Cellular Automata Simulation toolkit for Julia
Cellular Automata
A cellular automaton is a collection of "colored" cells on a grid of specified shape that evolves through a number of discrete time steps according to a set of rules based on the states of neighboring cells. The rules are then applied iteratively for as many time steps as desired.
mathworld.wolfram.com/CellularAutomaton
Elementary CA
To generate an elementary cellular automaton, use
ca = CellularAutomaton(rule, init, gen)
where rule is the Wolfram code (integer), init is a vector containing the initial starting condition and gen is the number of generations to be computed. For a single starting cell in the middle just omit the init vector.
To generate 15 generations of elementary cellular automaton of rule 90 use
using CellularAutomata
ca90 = CellularAutomaton(90, 16)

Totalistic CA
For a more complex cellular automaton you can change the number of states k the cell can be and the radius r of neighbors that can influence the states. If k is changed to be larger than 2, a totalistic CA is computed where only the average value of all neighbors count. This can be done like this
ca = CellularAutomaton(993, 15, k=3)

2 dimensional CAs
Two dimensional cellular automaton (like Conway's Game of Life) can be created by
ca = CA2d(B, S, init, gen)
where B and S are vectors that have the numbers of neighboring cells that define when cell is born or survives, init (matrix) is the initial starting condition and gen is the number of generations the CA is to be computed.
Game of life is then run for 9 generations for e.g. a turbine pattern by typing
ca = CA2d([3], [2, 3], init, 9)
