Figure 7: A GRN of three nodes and its attractor network.
From: A geometrical approach to control and controllability of nonlinear dynamical networks
(a) Schematic illustration of a three-node GRN system. The arrowhead and bar-head edges represent activation and inhibitory regulations, respectively. The sawtooth lines specify that the corresponding edge strength is experimentally adjustable. (b) Coexisting attractors (A to H) in the phase space. (c) The underlying attractor network, where each node represents an attractor and each weighted directed link indicates that its strength can be experimentally tuned to steer the system from the starting attractor to the pointed attractor. Each grey directed link with a single arrow indicates that only one parameter is needed to achieve control, and each purple link with a double-arrow and the label 3 represent the case where three parameters are required to achieve control.
