`Ian Weaver` Started a very [nice discussion in Slack](https://julialang.slack.com/archives/C67910KEH/p1623346392383700) that could use some more community input:

We want examples were Julia code matches the paper pseudo code or mathematical specification.

Here are some examples people fished from twitter, but we’d love to see yours!

I made some performance concessions to keep it close to the paper’s equations, like computing the inverse of A.

Here is the package version (unregistered): [GitHub - ew-git/PoissonFE.jl: Implements Poisson fixed effects regression and robust standard errors from Wooldridge (1999) in Julia. The implementation should be faster than GLM.jl with many fixed effects.](https://github.com/ew-git/PoissonFE.jl)

I recently coded up the implicit consumption aggregation calculation (non-homothetic CES) in

for integration with AD. Will be registered soon.

Thanks @miguelraz for the [BeautifulAlgorithms.jl](https://github.com/mossr/BeautifulAlgorithms.jl) shout-out!

I have a few LaTeX Overleaf projects that compare algorithmic pseudocode you’d find in an academic paper with their Julia implementation counterparts:

- **Overleaf** : [**Cross-entropy method**](https://www.overleaf.com/read/cxdjhgqmstfx) [1]  

- **Overleaf** : [**K-means clustering**](https://www.overleaf.com/read/ppdpncgmhcvk) [2]  

- **Overleaf** : [**Deep deterministic policy gradient (DDPG)**](https://www.overleaf.com/read/tsjrbxssbzgr) [3]
