Optimization of Sums of Bivariate Functions: An Introduction to Relaxation-Based Methods for the Case of Finite Domains

Nils Müller

We study the optimization of functions with $n > 2$ arguments that have a representation as a sum of several functions that have only $2$ of the $n$ arguments each, termed sums of bi…

Non-local Optimization: Imposing Structure on Optimization Problems by Relaxation

Nils Müller, Tobias Glasmachers

In stochastic optimization, particularly in evolutionary computation and reinforcement learning, the optimization of a function $f : Ω \to R$ is often addressed through opti…
