Solid lines are hills,
dotted are valleys
|
|
The boundaries between
basins are saddle points where we can get stuck (only move along them)
|
|
Slightest perturbation will put us in a basin
|
|
This occurs in continuous state spaces
|
|
But in a discrete state space, every possible state
may occur within a basin (as in Hopfield)
|
|
Note repeller (yellow) and
unstable attractor (blue) on the boundary in lower left quadrant
