Hi all, I’ve been interested in learning more about Zygote.jl and some ways I can use it in my optimization programs. Frankly, when terminology such as dual and primal are mentioned in the context of Zygotes mechanism, I don’t really understand their function, let alone the purpose for the implementation of duals and primals in the code. Can someone perhaps give me some direction on where to look for more information on dual and primals?

The best starting point is probably: Duality (optimization) - Wikipedia to the generality you are looking for.
