几何遗传算法由于其独特的变量染色体表达和简易的编解码方式特别适合于对具有封闭轮廓线的形状优化问题的求解(如翼型叶片的优化设计等)。本文首次将几何遗传算法应用于流体机械中离心扩压器叶栅叶型的改进设计，所取得的结果令人满意。

Geometric genetic algorithm is very suitable to solve the shape optimization problem with close contour, i.e., optimization of airfoil profile, for its particular chromosome representation of variables to be optimized and its easiness in coding and decoding process. In this paper, the geometric genetic algorithm is applied to improving the design for blade profile of a centrifugal diffuser cascade in fluid-machines. Numerical simulation shows that this algorithm is satisfactory.
