In this note we study multiple-ratio fractional 0--1 programs, a broad class of NP-hard combinatorial optimization problems. In particular, under some relatively mild assumptions we provide a complete characterization of the conditions, which ensure that a single-ratio function is submodular. Then ...
1 Introduction 1.1 What is Dynamic Programming? 动态规划就是将一个比较复杂的问题拆解为多个简单的子问题,转而将目标放在解决子问题的一般步骤上,最终结合所有...选择排序 选择排序的基本思想:初始时,有序区为0,每一趟在无序区中选出一个关键字最小的元素,然后与无序区第一个元素交换,然后无序区减1,有...
我们用states[0][0]=true和states[0][2]=true 来表示这两种状态。 第1个物品的重量也是2,基于之前的背包状态,在这个物品决策完之后,不同的状态有3个,背包中物品总重量分别是0(0+0),2(0+2 or 2+0),4(2+2)。我们用states[1][0]=true,states[1][2]=true,states[1][4]=true来表示这三种状态。

We study the mixed 0-1 knapsack polytope, which is defined by a single knapsack constraint that contains 0-1 and bounded continuous variables. We develop a lifting theory for the continuous variables. In particular, we present a pseudo-polynomial algorithm for the sequential lifting of the contin...
