An efficient and robust algorithm for computing multivariable root loci is proposed. This algorithm solves a set of characteristic equations by pivoting. The algorithm is based on Kuhn's algorithm for finding roots of a polynomial by pivoting. Some theoretical results which validate the algorithm are obtained and several examples are computed to show the efficiency of the algorithm.
