Paper bag problem

The "paper bag problem" generally refers to a conceptual puzzle or problem in computer science, mathematics, or optimization relating to how to efficiently pack items—often in a constrained space, like a bag—while maximizing the usage of that space or minimizing wasted space. However, it's important to note that the phrase "paper bag problem" might not refer to a widely recognized specific problem by that name; it often points toward more general concepts in combinatorial optimization, such as the knapsack problem.
