Abstract :
We introduce a dynamical system for direct optimization of objective functions defined on 𝒞p×q having unitary extremes. Then we give analytical results on the system´s stationary states and their stability. Finally, we show some existing well-known optimization systems drawn from the literature are special cases of the one presented here
