Hi, I was trying to explore solvers for multivariate functions in other CAS like Maple and Mathematica and Maxima, Here is the documentation I found about solvers in Maxima: https://github.com/andrejv/maxima/blob/master/share/algebra/solver/solver1-en.html I think we need to be very specific

Couldn't we still just number the roots? Or would that lead to inconsistencies? It would be fairly complicated to do in full generality. It is necessary to construct one root at a time. (This is essentially so in the complex case, too.) For each root one has to remove those that have

It should not be necessary to lose any of the current functionality of RootOf. A call will now return a complex value. It could be replaced with a call to rootof() which would do exactly the same. (Some editing would be needed in solvers, of course.) The field of complex numbers is special
