On Optimization Design Genetic Algorithms of Two-dimensional Supersonic Inlet Based

Simple genetic algorithms is introduced at first,and niche genetic algorithms evolve from simple genetic algorithms.A simple test function is used to test the two GAs,and compare them.And then optimization design of the two-dimensional supersonic inlet is carried out with niche gas.In singular-objective optimization design,the maximal total pressure recovery coefficient is the objective function;and in the multi-objective,not only is the maximal total pressure recovery coefficient is the objective function but also the boost pressure ratio.The results of the two are compared,after the optimization design
