The main contents are as follows:1.Basing on the SGA and uniting non-line taxis strategy , the improved genetic alogorithm program is presented in fortran language , and its feasibility is analyzed by a simple function.

• 在遗传算法原理的基础上,结合非线性排序策略和最优保存策略,用FORTRAN语言编制了改进的遗传算法程序。 从优化一个简单函数的实例入手,分析该程序的可行性。
