Regions of Attraction for Two Hidden Attractors

Paper presents the regions of attraction of two hidden attractors occurring in the dimensionless model of the Chua's circuit. For a long time it was thought that there is no attractor in the system; later, only one, so-called hidden attractor was discovered. In fact there are up to two hidden attractors close together. Therefore, not only the regions of attraction of two hidden attractors are shown in the paper, but it is pointed out the need to choose the right size and location of the test cuboid for detection the hidden attractor. At the same time, it is pointed out how the accuracy of Matlab solution can lead to (un)detection of two hidden attractors.
