Numerical localization visualization of attractors Because of many pictures of attracters in the article I think it would be good to add something about attractors visualization From computation point of view attractors can be naturally regarded as self exciting attractors or hidden attractors Self exciting attractors can be localized numerically by standard computational procedure in which after transient process a trajectory started from a point of unstable manifold in a small neighborhood of unstable equilibrium reaches an attractor and computes it such examples are classical attractor in Van der Pol Beluosov Zhabotinsky Lorenz and many others dynamical systems While basin of attraction of hidden attractors does not contain neighborhoods of equilibria and therefore hidden attractor can not be localized by standard computational procedure
