Query: Numerical aspects of evolution of plane curves satisfying the fourth
  order geometric equation   In this review paper we present a stable Lagrangian numerical method for
computing plane curves evolution driven by the fourth order geometric equation.
The numerical scheme and computational examples are presented.
