Approximating geometric crossover in semantic space

Pawel Lichocki

We propose a crossover operator that works with genetic programming trees and is approximately geometric crossover in the semantic space. By defining semantic as program's evaluation profile with respect to a set of fitness cases and constraining to a spec ...

Vibrational mode-specific reaction of methane on a nickel surface

Thomas Rizzo, Rainer Beck, Plinio Maroni, Thanh Tung Dang, Mathieu Schmid

The dissociation of methane on a nickel catalyst is a key step in steam reforming of natural gas for hydrogen production. Despite substantial effort in both experiment and theory, there is still no atomic-scale description of this important gas-surface rea ...
