摘要: In a multiattractor state of globally coupled dynamical system, stability the attractors is studied by recording return rates to themselves after perturbations. Besides basin volume, are characterized strength, defined as threshold perturbation for full rate. It observed that Milnor with vanishing strength dominant in partially ordered phase. Attractions weak found be often enhanced addition noise, selectively its amplitude. [S0031-9007(97)02844-5]
