The Proportional, Integral and Derivative (PID) controllers are widely used in industrial applications. Their popularity comes from their robust performance and also from their functional simplicity.

We present a new method based on evolutionary algorithms which permits to determine efficiently the ground state of the time-independent Schrödinger equation for arbitrary external potentials. The approach relies on the variational principle. The ground-state wave function of a given...

Can we build computers that are intelligent and alive? This question has been on the minds of computer scientists since the dawn of the computer age and remains a most compelling line of inquiry. Some would argue that the question makes sense only if we put scare quotes around "intelligent" and...
