CBC and MIP from web assembly/pyodide

[sebastianjhm]

Hi CBC team.
I'm working in my project and I want to use MIP and CBC in the browser with pyodide. MIP function good because is a pure pyrhon library, the problem is CBC. I had trying with cbcpy but the wheels are from specific OS. Is possible achieve use CBC with web assembly, or convert to a pure python library?

Years ago, I managed to compile SYMPHONY with emscripten as a proof of concept, so you can just give it a try and you may succeed. But I really doubt it makes sense to try to run a MIP solver in-browser. You would likely be much better off running it server-side. You certainly cannot convert Cbc to pure Python and even if you could, that would likely result in a catastrophic loss of efficiency.

I've been developing a MIP solver in pure Python, but only for educational purposes and as a way of doing proofs-of-concept of simple ideas. It certainly wouldn't have performance anywhere near Cbc. Of course, if you're just hoping to solve very small/easy MILPs, it would work.

I understand,
For very small/easy MILPs, in pyodide is GLPK. My question was because CBC is a better solver. But thanks for the info.
