背包问题(Knapsack Problem)是一种经典的组合优化问题,通常描述为:给定一组物品,每个物品都有特定的重量和价值,在限定的总重量内,如何选择物品,使得所选物品的总价值最大。这里,我将为你详细介绍背包问题的定义、基本类型,并给出一个基于动态规划的Python实现。 1. 背包问题的定义 背包问题可以形式化描述为:给定一...

\(a \in \mathbb {r}^k\) . we refer to ( 1a )–( 1c ) as the upper-level and to ( 1d ) as the lower-level problem. note that problem ( 1 ) is a min-max problem. hence, the follower’s response yields the worst-possible outcome for the leader, which is why there ...
