Problem description: N items and a backpack are given. The Weight of item I is W [I], the value is V [I], and the size of the backpack is C. Q: How should I select the items to be loaded into the backpack to maximize the total value of the items in the backpack?
Analysis: For an item, either a backpack or no package is loaded. Therefore, the loading status of an item can be 0 or 1. Set the loading status of

0-1 knapsack problem0-1 Basic idea of knapsack problem:P[i,j] Represents the maximum value of the value of J when the total value of the first I item, Str[i, J] represents the value of the item weight string when the total value of the first I item is the maximum value of J. i=0 or j=
Given a group of items, each item has its own weight and value. within the defined total weight, how can we choose to make the total price of the item the highest.
Solution: value density PI/wi (PI indicates the value of the item I, and WI indicates the weight of the item I) greedy algorithm. This selection criterion is: select the item with the highest PI/wi value from the remaining item.
