Using two-valued bisection search to get the PSS representation of the multistationarity region. a The reaction network under study. This network has two conservation laws, thus two of the six steady state equations may be replaced by linear invariants. b The system of equations for studying multistationarity. c The CAD representation of the multistationarity region. d–f Approximations of the multistationarity region computed by Algorithm 1. g–h PSS representations of degrees 2 and 4 computed from the union of yellow rectangles in f as K. i PSS representations of degree 4 computed from 140 sample points from the union of yellow rectangles in f as approximation of K
