first fit decreasing算法的原理 First Fit Decreasing (FFD)算法是一种针对装箱问题的改进算法。在传统的装箱问题中,物品按照顺序依次装入箱子,如果当前物品不能放入任何一个已有的箱子中,则开启一个新的箱子。然而,这种做法可能会导致空间的浪费,因为可能存在一些箱子只装了一部分物品,而其他物品则被放入新的箱子中...

First.Fit算法:将物件1放入箱1中,当要放物件,时,将其放入最小序号 且其当前物件量不超过1一wf的包中。Best.Fit类似于First.Fit除了它是将物件., 放入当前物件量最大且不超过1一w,外。First.Fit Decreasing先将物件按尺寸非增 排序然后利用FF法则。类似地,Best.Fit Decreasing先将物件按尺寸非增排序然 后利...
常见的算法:NF(Next Fit)近似算法,FF(First Fit)近似算法,FFD(First Fit Decreasing)近似算法,BF(best Fit),BFD(Best Fit Deceasing)等, 下次适应算法(NF, Next Fit):NF算法是最简单也是最早研究的一个算法,它的处理方法是始终维持一个当前打开的箱子,对于每一个要装入的物品,检查该物品是否可以放入当前打开...
