Intermingled basins due to finite accuracy

A chaotic map interrupted by two small neighborhoods and a periodically tilted box within which disorderly colliding disks can reach different attracting configurations was investigated numerically, each containing an attracting point. For finite, arbitrarily small accuracy, both systems have basins of attraction that are indistinguishable from intermingled basins. Results show that bifurcation destabilizing the fixed points or the disk configurations causes on-off intermittency.
