this paper proposes an improved genetic algorithm with varying population size that achieved the goal of keeping the variety of the population through adding complementary operator in adjusting population size.

the results of calculation examples show that the presented model is reliable and effective and its calculation accuracy and speed can be further improved by adding special operator.

算例结果表明，该模型可靠有效，加入特殊算子改进后，可进一步提高计算精度和运算速度。
