Bertini

Collection Details Full Record

Description

Bertini is a software package for numerically solving systems of polynomial equations. It can find both isolated solutions as well as positive-dimensional solutions.

Bertini is the product of a research program in numerical algebraic geometry. It uses many newly developed methods, including intersecting and projecting algebraic sets, adaptive precision path tracking, methods for treating singular sets, parameter homotopies, user-defined path tracking, and other new research.

    Abstract:

    Dedicated to our collaborator, mentor, and friend, Andrew Sommese, by Bates, Hauenstein, and Wampler on the occasion of his sixtieth birthday.

    When numerically tracking implicitly-defined paths, such as is required for homotopy continuation methods, efficiency and reliability are enhanced by using adaptive stepsize and adaptive multiprecision methods. Both efficiency and reliability can be further improved by adapting precision and stepsize simultaneously. This paper presents a strategy fo…
