The low efficency arise from two factors : one is that we do n ' t understand multibody system as deep as possible, resting on " there are so many trees as one ca n ' t see the forest ". the other is that the algorism should hardly avoids void computing possiblly - - adding, minusing or multipling by zero, and ca n ' t reach the precision computing - - each computing is necessary, and the latter computing use the formal results as it can as as possible
計算效率不高的原因有二、一是對機械多體系統認識深刻程度不夠，停留在「只見樹木，不見森林」的層次上；二是演算法上應該竭力避免虛運算? ?與零相加減、與零相乘和重復運算等，但由於多體系統動力學的復雜性、強非線性和人們對其認識現有深度的不夠，故未能實現所謂的「精益運算」 ? ?每步運算皆為必須，且后續運算應盡能借用已有結果。 -
The experimental results have proved that the ga measure is a relative effective measure, and the combination of adding - minusing classes measure and row - column measure is better. second, we research two attributes reduction measures
實驗結果表明：基於遺傳演算法的離散法是一個相對較好的離散化方法，增類減類離散法與行列離散法是相對較佳的一對方法組合。
