文摘:本文通過對遺傳建模和公式發現進行分析，提出了基於遺傳建模的公式發現演算法，並給出了具體的描述，對演算法中關鍵對象的數據結構給出了具體的設計，最後針對數列歸納和公式發現給出了運行結果。 -
Unless you have a very good understanding of the fitness formula in which case, you probably don t need the genetic algorithm anyway, setting a fitness goal can result in either infinite loops, or an individual who is only " good enough. " third, you can exit the algorithm after a set number of iterations, or " generations.
除非對適應性公式非常了解（在這種情形下，無論如何，您都可能不再需要遺傳演算法了） ，設定適應性目標的結果，或者是導致無窮循環，或者是得到一個僅僅是「足夠好」的個體。第三，在迭代了一定的次數或者說經歷了一定數目的「代」后，您也可以退出。 -
