引言 机械优化设计是最优化理论、电子计算机技术与机械工程相结合的一门学科。早在二十世纪五十年代以前,工程设计问题的最佳决策还只是限于古典数学中的微分法和变分法,或用拉格朗日乘子法解决等式约束问题。直到四十年代前后,特别是Dantzing提 Introduction Mechanical optimization design is the optimization theory, a combination of electronic computer technology and mechanical engineering. As early as the 1950s, the best decision-making on engineering design problems was confined to differential and variational methods in classical mathematics or to the problem of equality constraints using Lagrange multipliers. Until the 1940s, especially Dantzing mentioned
