No, the article we are discussing here used a GPU solver implementing the primal-dual hybrid gradient method, which cannot do any of those things. (This is not the same thing as the simplex algorithm from the 01940s. I was wrong about that.) The LLM discussed in the previous work was not in fact able to do that itself. Like a normal person, it wrote a Python program to do it.

While the apparent advent of AGI is indeed really crazy, the point of this article is sort of the opposite.
