The new book he published with Cottrell and Dapprich is called Economic Planning in an Age of Climate Crisis. It's short but good. On libgen.

You may just want to look into some of Kantorovichs work on linear programming, like The Best Use of Economic Resources.

Here are a few other things:

Receding Horizon Planning, Zacharia

Apolito, Aurora. ‘The Problem of Scale in Anarchism and the Case for Cybernetic Communism’. IIRC the author (via a pen name) is a Caltech physicist

Tomas Haerdin, Swedish researcher. He has a website with some stuff. https://www.haerdin.se/category/blog.html

Dapprich's dissertation: Dapprich, Jan Philipp. ‘Rationality and Distribution in the Socialist Economy’. It was okay. He co-authored cockshitts new book I mentioned above.

Casperforum.org. A bit dead, but you may find something of interest.

I have some more references but I'm on my phone. I'll try to remember to add more later.

I recently found this: Mathematics to plan an economy: an introduction to cyber-socialist calculation

It's a book about the mathematics and algorithmic of economic planning. You can download it for free from this site.

If you want to look into actual algorithms I'm pretty sure that Cockshott himself has published papers on his proposed algorithms. Last time i read New Socialism I'm pretty sure he mentioned them by title.
