Abstract
Introduces an algorithm to solve a stability robustness problem by using differential topological concepts based on symbolic computation. Despite the well-known results shown that the real robustness margin problem is NP hard, this paper shows that we can achieve the accurate robustness margin of the grid method without suffering the troublesome complexity of the grid method
