Snake-ising model

[Francesco215]

We need an animation that draws lots of circles in a snake pattern like the one of the website

As usual each node can have two possible values (0 or 1), so they can have two colors WHITE or BLACK, and we also need a function that animates the color changes. Maybe we can just reuse the update_fill function already present in the code

Each circle will be connected by a segment with the color=hamiltonian_color

i'd say that is better to put the code in a separate python file inside the project folder

Tip

In the website code i wrote a function that returns the realtive position in a $i,j$ grid of all the elements in the serpentine, i think translating this in python this will make your job easier.

I don't know how deep i have to go into the explanation of this function, but printing the output a couple of times should be enough. if you need any clarifiaction you can always ask

function Serpentine(i, nSH) {
        //nSH represents the variable numSpinsHorizontal
        if (i<nSH) return [i, 0]
        if (i==nSH) return [nSH-1, 1]
        if (i<=2*nSH) return [2*nSH-i, 2]
        if (i==2*nSH+1) return [0,3]

        let recursive=Serpentine(i%(2*(nSH+1)),nSH);
        recursive[1]+=4*Math.floor(i/(2*nSH+2));

        return recursive
}
