Decidability/Undecidability of feasibility of optimization problems
$begingroup$
I build "on top of" the posts "Is the feasibility of a system of non-convex quadratic equations and inequations decidable?" and "Is the first-order theory (with =) of real numbers with addition and multiplication complete and decidable?" My understanding is that all coefficients in question can be algebraic numbers. Question: Can the coefficients be replaced by computable real numbers? I doubt that this is the case because algebraic numbers can be specified with polynomial equalities and inequalities whereas (I think), general non-computable reals cannot. However, my knowledge is lacking and I'd be thankful for an answer.

If you are going to reference other posts, you should link to them. You can use the linked chain icon in the posting box, but I prefer the simpler syntax[ visible text ](address)
