Exact Optimization via Sums of Nonnegative Circuits and Sums of AM/GM Exponentials
Victor Magron, Henning Seidler, Timo de Wolff
We provide two hybrid numeric-symbolic optimization algorithms, computing exact sums of nonnegative circuits (SONC) and sums of arithmetic-geometric-exponentials (SAGE) decompositi…

Lopsided Approximation of Amoebas
Jens Forsgård, Laura Felicia Matusevich, Nathan Mehlhop +1
The amoeba of a Laurent polynomial is the image of the corresponding hypersurface under the coordinatewise log absolute value map. In this article, we demonstrate that a theoretica…
