Tarski's theorem shows that the theory of real closed fields is decidable. In section 1.3 of this presentation http://mat.msgsu.edu.tr/~aad/2012/Slides/tressl.pdf, it says that Abraham Robinson generalized this result to the theory of real closed fields in a language expanded with a predicate saying "I am algebraic". Does anyone know a reference for this result? Thanks
