摘要
利用能量法及最小二乘法建立曲线优化数学模型,同时应用罚函数法将有约束多目标优化问题转变为无约束优化问题,并采用遗传算法进行曲线优化。通过实例验证了算法的有效性,并将此法应用到曲面优化设计中,得到了较好结果。
The mathematical model of the curve which would be optimum has been built applying the methods of Energy and Least Squares Technique ,the constrained optimization problems are changed into the unconstrained optimization using the penalty function,and optimum the curves by Genetic algo-rithm. The method has been put into the proof validly,finally used to optimum the surfaces ,and obtained the better result.
