摘要: 提出将改进的实码加速遗传算法(RAGA)与投影寻踪评价模型(PPE)相结合,同时优化多维参数(投影方向),建立了多元数据分类与评价模型。对长春南湖水的营养状态做出了评价,取得满意效果,为水质分析与评价提供一种新的方法与思路。

Abstract: The authors improved the traditional genetic algorithm, and combined the new method named RAGA (Real coding based on Accelerating Genetic Algorithm) with PPE (Projection Pursuit Evaluation) model. The RAGA-PPE model can optimize several parameters at one time. Based on this method, the authors built up a new evaluating model. Through applying the new model to evaluating the water nutrient states of South Lake in Changchun, the authors gained the good results. Thus, the authors provided an new method and thought for readers who engage in researching the water quality evaluation.
