Self-organizing logic gates formed from a combination of memristor devices and dynamic correction modules configured to provide a stable operation upon application of a signal to any terminal A SOLG of the invention can accept signals from any terminal and does not require an absence of signals at any other terminal. Terminal signals can superpose and the gate finds equilibrium, if an equilibrium exists.

A method of controlling an electricity production station including at least one renewable energy source and an energy accumulation system, allowing an operator to commit, at an electrical distribution network manager, to a power profile P.sub.G that the station will be able to deliver over a forthcoming time period. The declared power profile must, furthermore, comply with constraints imposed by the manager of the electricity distribution network. Non-compliance with this commitment may be subject to penalties. It is then incumbent on the operator to best optimize the method of controlling the electricity production station so as to maximize the electrical power fed into the network, while complying, in so far as possible, over a certain tolerance range, with the power profile commitment P.sub.G.

An NP-processor is provided that is based on a computing environment consisting of a finite set of multiple-element triggers that are interconnected by common elements. The NP-processor has interference relations between the computing environment elements. Negative feedback is introduced and is intended for isolating an active state, which is the solution to the problem, from an exponential number of modes of oscillation in the computing environment.
