A novel binary Kepler optimization algorithm for 0–1 knapsack problems: Methods and applications

open access: yesAlexandria Engineering Journal, 2023
The 0–1 Knapsack problem is a non-deterministic polynomial-time-hard combinatorial optimization problem that cannot be solved in reasonable time using traditional methods.

The RaPID-Ω system: Room and proctor intelligent decider for large scale tests programming [PDF]

open access: yesYugoslav Journal of Operations Research, 2021
We present the documentation and mathematical modeling of the open-box system RaPID/Ω. The software is designed for the choice of classrooms and the assignment of proctoring duties in massive tests, which is a common situation in educational institutions

Time-constrained restless bandits and the knapsack problem for perishable items (Extended Abstract) [PDF]

open access: yes, 2007
Motivated by a food promotion problem, we introduce the Knapsack Problem for Perishable Items (KPPI) to address a dynamic problem of optimally filling a knapsack with items that disappear randomly.

Binary Moth Search Algorithm for Discounted {0-1} Knapsack Problem

open access: yesIEEE Access, 2018
The discounted {0-1} knapsack problem (DKP) extends the classical 0-1 knapsack problem (0-1 KP) in which a set of item groups is included and each group consists of three items, whereas at most one of the three items can be packed into the knapsack ...

Parameterized Approximation Schemes for Independent Set of Rectangles and Geometric Knapsack [PDF]

open access: yes, 2019
The area of parameterized approximation seeks to combine approximation and parameterized algorithms to obtain, e.g., (1+epsilon)-approximations in f(k,epsilon)n^O(1) time where k is some parameter of the input.

A Memetic Lagrangian Heuristic for the 0-1 Multidimensional Knapsack Problem

open access: yesDiscrete Dynamics in Nature and Society, 2013
We present a new evolutionary algorithm to solve the 0-1 multidimensional knapsack problem. We tackle the problem using duality concept, differently from traditional approaches. Our method is based on Lagrangian relaxation.

Multi-Objective ABC-NM Algorithm for Multi-Dimensional Combinatorial Optimization Problem

open access: yesAxioms, 2023
This article addresses the problem of converting a single-objective combinatorial problem into a multi-objective one using the Pareto front approach. Although existing algorithms can identify the optimal solution in a multi-objective space, they fail to ...

An Exact Algorithm for Bilevel 0‐1 Knapsack Problems [PDF]

open access: yesMathematical Problems in Engineering, 2012
We propose a new exact method for solving bilevel 0‐1 knapsack problems. A bilevel problem models a hierarchical decision process that involves two decision makers called the leader and the follower. In these processes, the leader takes his decision by considering explicitly the reaction of the follower.

Binary light spectrum optimizer for knapsack problems: An improved model

open access: yesAlexandria Engineering Journal, 2023
This paper presents a binary variant of a novel physics-based meta-heuristic optimization algorithm, namely Light spectrum optimizer (LSO), for tackling both the 0–1 knapsack (KP01) and multidimensional knapsack problems (MKP).

Solving Multidimensional 0-1 Knapsack Problem with Time-Free Tissue P Systems

open access: yesJournal of Applied Mathematics, 2014
Tissue P system is a class of parallel and distributed model; a feature of traditional tissue P system is that the execution time of certain biological processes is very sensitive to environmental factors that might be hard to control.
