Shape-GA2 does the same as Shape-GA1 meanwhile. The calculation of each shape fitness requires to solve the flow equations by CFD solvers over the whole domain. Combining DDM with the local geometrical optimization, the flow field can be solved separately by two followers Flow-GA1 and Flow-GA2 in each subdomain. The flow-GAs returns the current fittest flow solution to Shape-GAs for computing fitness of each shape and the information exchange between two followers happens during the exchange between the shape players.

2. W -cycle preconditioner based on piecewise constant coarse spaces using one pre- and post-smoothing steps of symmetric Gauss-Seidel smoother. 3. variable V -cycle preconditioner based on continuous elements described in Section 3 with one pre- and post-smoothing Gauss-Seidel iteration on the finest level and double the pre- and post-smoothing iteration on each consecutive coarser level. The numerical results are summarised below. In each table we give the number of iterations in the PCG algorithm and the corresponding average reduction Preconditioning of DG Methods 41 factor for each test run.
