Further, two additional robustness measures inspired by numerical experiments and literature are discussed. Cell Agglomeration and solution reinitialization are used to prevent the optimization algorithm from stagnating at an undesired local minimum. Lastly, the methods capabilities are demonstrated on a sequence of two-dimensional problems of increasing difficulty (Space-Time Advection, Space-Time Burgers, Steady 2D Euler Equations) and discussed by means of a convergence study.
