Abstract: 
An efficient formulation for the robust shape optimization of aerodynamic objects is ‎introduced in this paper. The formulation has three essential features. First, an Euler ‎solver based on a second-order Godunov scheme is used for the flow calculations. ‎Second, a genetic algorithm with binary number encoding is implemented for the ‎optimization procedure. The third ingredient of the procedure is the use of previous ‎flow that is closest in terms of geometric parameters to the new shape as an initial ‎condition for the new function evaluation. This makes the solution towards the final ‎value progressively faster and reduces the computer time for the convergence of the ‎algorithm. The algorithm is used to optimize two different problems, a simple bump ‎problem, and a two-dimensional transonic airfoil problem using an Euler solver solver ‎equation. The results indicate that GA/flow algorithm is robust and can optimize a ‎wide range of problems with a minimum implementation effort.
