Does anyone have any great examples of a document that explains an algorithm?
For work, I am trying to learn how an algorithm works, and I thought it'd be a great exercise to build up a doc that outlines what happens and how it works. I'm hopefully to lean slightly on the more technical side, but not so far that non-technical people won't derive any meaning.
I'm looking to write something that clearly outlines a process, and shows how those pieces affect the final result. It's something I've never done before, but having difficulty finding posts when googling around for "how an algorithm works".
I'm thinking the ideal format mixes both text and graphics, but the majority I have found are gigantic walls of text. I want to write about a software algorithm, but I think this broadly applies for any sort of complicated process.

Need to apply lacquer on a mild steel product that is zinc plated and has some vibratory surface polishing on top of it, which wears the zinc down a bit.
Need to pass 500 hours on a British Standard salt spray test (BS EN ISO 9227: 2017)
If anyone has any sources on a good lacquer supplier please let me know. Tried one by LVH coatings but it didn't pass more than 300 hours.

I've been having issues with powdercoating on top of zinc plated mild steel sometimes. Have issues like small dots visible instead of a smooth texture.
It looks like how a zit or pimple looks on the skin.
After zinc plating, it is pre heated for 15 mins at 150 degrees celsius. Then sand it with some 80 no sandpaper. Finally powder coat it and cure it again for 20 mins.
Amy inputs would be appreciated. Thanks guys.

Edit:
Hi guys, I posted recently about facing issues with powdercoating zinc plated mild steel. And I'm really thankful for all the responses I got. The zit like small dots I had last time were pretty much solved with outgassing.I am now facing another issue where the product has sort of tiny indents or pinholes. I can get my nail in them. Shared some photos below. If you guys could shed some light on what these are and why this is happening despite outgassing, it would be great.
Currently outgassing the parts at 250 degrees celsius for 30 mins. The curing temperature after that is 200 degrees celsius for 20 mins.
