The learning rate alpha is then multiplied by m and divided by the square root of v, to calculate an adjusted derivative to use for gradient descent.

But the code below shows

float adjustedDerivative = alpha * m / v;

Is this a typo?

I haven't played with my code for drawing hyperbolic sphere packings for two years, here are some new images, each one comes from a different Coxeter group and takes 2 hours to render:

Glad to see my animation showcasing the limit set of a hyperbolic group featured on shadertoy this week!

Is this the first time they featured a pure mathematics work on their front page?
