Dynamic Planning: backpack problems, dynamic planningBackpack Problems There are N items and a backpack with a capacity of V. The size of the I item is c [I], and the value is w [I]. Solving which items are loaded into a backpack can maximize the total value. State transition equation: F [I] [v] = max (f [I-1] [v], f [I-1] [v-c [I] + w [I]) This equation

When I was a beginner, I tried to solve the problem with greedy ideas, but I still couldn't think of it for more than an hour. // The two parameters F [k] in Max, and f [k-weight [I] + value [I] indicate the maximum value when the backpack capacity is K. // F [k] Is this meaning, not to mention. // While F [k-weight [I] + value [I] also indicates the maximum value when the backpack capacity is K. Why? // Fi

We regard patience as the size of the backpack, experience as the value, and increase the number of one-dimensional constraints. This is a typical knapsack problem. We define DP [J] [k] to indicate that the backpack capacity is J, and select the maximum value that K items can achieve. In fact, this is the result of the previous dimension omitted. We can clearly define DP [I] [J] [k] to indicate the items
