遗传编程足一种具有自动选择输入变量、自动确定模型结构特性的新的建模方法.在分析了遗传编程进化速度慢的因为后,采用新的适应值调整方法,改善了进化速度.将该方法用于低浓打浆过程的动态建模的结果显示,依此建立的模型能较好地反映打浆过程的动态特性.
遺傳編程足一種具有自動選擇輸入變量、自動確定模型結構特性的新的建模方法.在分析瞭遺傳編程進化速度慢的因為後,採用新的適應值調整方法,改善瞭進化速度.將該方法用于低濃打漿過程的動態建模的結果顯示,依此建立的模型能較好地反映打漿過程的動態特性.

Genetic programming(GP)can derive both a model structure and its parameter values,and GP is a novel technique of process modeling.After the cause of slow evolution of GP is analyzed,a novel fitness stimulating method is introduced into GP to improve the evolution of GP.The method is applied to establish the model of low consistency refining,and results show that the model can well reveal the dynamic performances of stock refining process.
