text: Popular growth models include:
  * KPZ equation
  * Dimer model
  * Eden growth model
  * SOS model
  *Self-avoiding walk
  *Abelian sandpile model
  *Kuramoto–Sivashinsky equation (or the flame equation, for studying the surface of a flame front)
  They are studied for their fractal properties, scaling behavior, critical exponents, universality classes, and relations to chaos theory, dynamical system, non-equilibrium / disordered / complex systems.
  Popular tools include statistical mechanics, renormalization group, rough path theory, etc.
