Outline of Final Research Achievements

We proposed highly reliable symbolic-numeric computation methods for algebraic problems with empirical data. Some main results are as follows. (1) Algorithms to compute perturbation bounds for preserving properties of solutions of a polynomial system. (2) An algorithm to compute the nearest polynomial to multiple given polynomials with a given zero. (3) A new application of stabilization techniques.
