Does anyone know any good and usable software package, preferably in Windows, that can effectively find SOS (sum of squares) polynomials $s_{0}\left(x\right)$ and $s_{1}\left(x\right)$ for any real polynomial $f\left(x\right)\ge0$ on $\left\{ x\in\mathbb{R}:g\left(x\right)\ge0\right\} $ where $g\left(x\right)$ is a real polynomial, such that $$ f\left(x\right)=s_{1}\left(x\right)g\left(x\right)+s_{0}\left(x\right)? $$ Many thanks.
