Abstract: Weispfenning has shown how to use test term methods for quantifier elimination in linear and quadratic first-order formulas over real closed fields. This paper describes the state of the implementation of such methods in the computer algebra system Risa/Asir. The package described here is entirely written in the C programming language. We point on possible extensions of the package and give examples for automatic quantifier eliminations performed by Risa/Asir. Key words: real quantifier... (Update)
