New Optimization Algorithms to Calculate Roots of Polynomials

[Thomas Klemm]

From the linked slides "Condition Numbers of Numeric and Algebraic Problems":

Quote:Condition number of a root of a univariate polynomial
(…)
Toh and Trefethen (Gautschi): condition number of
root x^∗ (relative perturbation to p, absolute
perturbation to x^∗) is . . . Exercise: FIGURE IT
OUT!

That's the spirit we like.
No worries. It's revealed on the next slide.

Cheers
