Minimizing Rational Functions by Exact Jacobian SDP Relaxation Applicable to Finite Singularities
Feng Guo, Li Wang, Guangming Zhou
This paper considers the optimization problem of minimizing a rational function. We reformulate this problem as polynomial optimization by the technique of homogenization. These tw…
