Fine-grained timing using genetic programming

In previous work, we have demonstrated that it is possible to use Genetic Programming to minimise the resource consumption of software, such as its power consumption or execution time. In this paper, we investigate the extent to which Genetic Programming can be used to gain fine-grained control over software timing. We introduce the ideas behind our work, and carry out experimentation to find that Genetic Programming is indeed able to produce software with unusual and desirable timing properties, where it is not obvious how a manual approach could replicate such results. In general, we discover that Genetic Programming is most effective in controlling statistical properties of software rather than precise control over its timing for individual inputs. This control may find useful application in cryptography and embedded systems

Simulating 0+1 Dimensional Quantum Gravity on Quantum Computers: Mini-Superspace Quantum Cosmology and the World Line Approach in Quantum Field Theory

Quantum computers are a promising candidate to radically expand computational science through increased computing power and more effective algorithms. In particular quantum computing could have a tremendous impact in the field of quantum cosmology. The goal of quantum cosmology is to describe the evolution of the Universe through the Wheeler-DeWitt equation or path integral methods without having to first formulate a full theory of quantum gravity. The quantum computer provides an advantage in this endeavor because it can perform path integrals in Lorentzian space and does not require constructing contour integrations in Euclidean gravity. Also quantum computers can provide advantages in systems with fermions which are difficult to analyze on classical computers. In this study, we first employed classical computational methods to analyze a Friedmann-Robertson-Walker mini-superspace with a scalar field and visualize the calculated wave function of the Universe for a variety of different values of the spatial curvature and cosmological constant. We them used IBM's Quantum Information Science Kit Python library and the variational quantum eigensolver to study the same systems on a quantum computer. The framework can also be extended to the world line approach to quantum field theory.Comment: 5 pages, 4 figure

El impacto de la globalización sobre la estructura de las relaciones laborales en Alemania

[Resumen] Este artículo aborda el impacto de la globalización sobre el Derecho del Trabajo alemán, sobre la base de la internacionalización de los mercados de trabajo. Apunta las consecuencias negativas de dicho impacto, especialmente las ligadas a deslocalizaciones. Apunta también el esperanzador futuro del modelo social alemán ligado a los desarrollos previsibles del Derecho colectivo del Trabajo de la Unión Europea.[Abstract] This article deals with the impact of globalisation on the German Labour Law, on the basis of the internationalization of the labour markets. It points out the negative consequences of such an impact, specially the ones linked to shifts of production. It also analyzes the hopeful future of the German social model linked to the prospective developments of the collective Labour Law of the European Union
