Knapsack problem with multiple constraints
http://masc.cs.gmu.edu/wiki/KnapsackProblems WebJan 19, 2024 · Now my question is whether this problem is a knapsack. I have done some research into the problem and found for example this source Algorithms for Knapsack Problems quite helpful. He seems to suggest in chapter 1.3.1 that one can merge the constraints and replace them with ∑ i = 1 n ( w i 1 + λ w i 2) x i j ≤ 0

WebYes. More precisely, for any fixed number of constraints (for example, weight and volume) the problem has a pseudo-polynomial time algorithm based on dynamic programming. … WebMay 4, 2024 · $\begingroup$ At a minimum, you could solve it as a multiple knapsack problem by setting the weights in the second constraint to one. There might be a better algorithm than this, however. There might be a better algorithm than this, however.
WebMar 1, 1978 · The Multiple Multidimensional Knapsack Problem with Family-Split Penalties (MMdKFSP) is introduced as a new variant of both the more classical Multi-Knapsack and … WebKnapsack Problems are the simplest NP -hard problems in Combinatorial Optimization, as they maximize an objective function subject to a single resource constraint. Several variants of the classical 0–1 Knapsack Problem will be considered with respect to relaxations, bounds, reductions and other algorithmic techniques for the exact solution.

WebFeb 6, 2024 · 1 Answer Sorted by: 3 I think the problem is NP-hard since: it will reduce to the 0-1 Knapsack problem with an equality constraint; and, changing ≤ to = in the 0-1 Knapsack constraint does not change its complexity (see explanation below). So, your problem is NP-hard as 0-1 Knapsack is.
