Computing with signals: a generic and modular signal machine for satisfiability problems
Abstract
Signal machines are an abstract and geometrical model of computation, where computations consist in colored segment lines and their intersections in the Euclidean plane. In this talk, we first introduce the model and give some basic properties, and then we illustrate the power of signal machines by a geometrical construction solving Q-SAT in bounded space and time, by the use of space-time continuity. We will also discuss some new complexities measure, more adapted to signal machines
