On the Robust Knapsack Problem [PDF]

open access: yesSIAM Journal on Optimization, 2013
We consider an uncertain variant of the knapsack problem that arises when the exact weight of each item is not exactly known in advance but belongs to a given interval, and the number of items whose weight differs from the nominal value is bounded by a constant.

On the rectangular knapsack problem: approximation of a specific quadratic knapsack problem [PDF]

open access: yesMathematical Methods of Operations Research, 2020
AbstractIn this article, we introduce the rectangular knapsack problem as a special case of the quadratic knapsack problem consisting in the maximization of the product of two separate knapsack profits subject to a cardinality constraint. We propose a polynomial time algorithm for this problem that provides a constant approximation ratio of 4.5.

On the rectangular knapsack problem

open access: yesMathematical Methods of Operations Research, 2022
AbstractA recent paper by Schulze et al. (Math Methods Oper Res 92(1):107–132, 2020) presented the Rectangular Knapsack Problem (Rkp) as a crucial subproblem in the study on the Cardinality-constrained Bi-objective Knapsack Problem (Cbkp). To this end, they started an investigation into its complexity and approximability.

Knapsack problems in products of groups [PDF]

open access: yes, 2015
The classic knapsack and related problems have natural generalizations to arbitrary (non-commutative) groups, collectively called knapsack-type problems in groups. We study the effect of free and direct products on their time complexity.

A Deep Reinforcement Learning-Based Scheme for Solving Multiple Knapsack Problems

open access: yesApplied Sciences, 2022
A knapsack problem is to select a set of items that maximizes the total profit of selected items while keeping the total weight of the selected items no less than the capacity of the knapsack.

A novel approach for solving travelling thief problem using enhanced simulated annealing [PDF]

open access: yesPeerJ Computer Science, 2021
Real-world optimization problems are getting more and more complex due to the involvement of inter dependencies. These complex problems need more advanced optimizing techniques.

Improved Online Algorithms for Knapsack and GAP in the Random Order Model [PDF]

open access: yes, 2019
The knapsack problem is one of the classical problems in combinatorial optimization: Given a set of items, each specified by its size and profit, the goal is to find a maximum profit packing into a knapsack of bounded capacity.
