Finding algorithm of optimal subset structure based on the Pareto layers in the knapsack problem

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2020
An algorithm is developed for finding the structure of the optimal subset in the knapsack problem based on the proposed multicriteria optimization model.

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

open access: yesSedimentology, EarlyView.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Dual population-based incremental learning for problem optimization in dynamic environments [PDF]

open access: yes, 2003
Copyright @ 2003 Asia Pacific Symposium on Intelligent and Evolutionary SystemsIn recent years there is a growing interest in the research of evolutionary algorithms for dynamic optimization problems since real world problems are usually dynamic, which ...

ATHLETIC: An exoskeleton countermeasure exercise device for resistive and plyometric training in deep‐space missions

open access: yesExperimental Physiology, EarlyView.
Abstract Prolonged exposure to weightlessness leads to loss of muscle and bone mass. Therefore, astronauts on board the International Space Station (ISS) currently perform mandatory daily exercises. ISS missions usually last 6 months, and future missions will become significantly longer when going, for example, to Mars.

Machine Learning-Driven Optimization for Solution Space Reduction in the Quadratic Multiple Knapsack Problem

open access: yesIEEE Access
The quadratic multiple knapsack problem (QMKP) is a well-studied problem in operations research. This problem involves selecting a subset of items that maximizes the linear and quadratic profit without exceeding a set of capacities for each knapsack ...

Performance of an S‐metolachlor capsule suspension for barnyardgrass control and crop tolerance in fenclorim‐treated rice

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Barnyardgrass [Echinochloa crus‐galli (L.) P. Beauv.] is the most problematic weed of delayed‐flooded rice (Oryza sativa L.) systems in the mid‐southern United States. Recent findings suggest that acetochlor can achieve effective barnyardgrass control in rice, but rice injury can occur with rainfall soon after application.

Generation Methods for Multidimensional Knapsack Problems and their Implications [PDF]

open access: yesJournal of Systemics, Cybernetics and Informatics, 2007
Although there are a variety of heuristics developed and applied to the variants of the binary knapsack problem, the testing of these heuristics are based on poorly defined test problems.

Growth and yield response of cashew (Anacardium occidentale L.) clones to spacing in the Guinea Savanna zone of Ghana

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract The Guinea Savanna zone of many countries constitutes a critical cashew‐producing area. Despite its importance, data‐driven recommendations on optimal tree spacing remain largely unavailable to farmers in Ghana. This knowledge gap constrains productivity, reduces returns on investment, and affects farmer interest and ultimately the long‐term ...

Two Knapsacks Are Better than One for Both Soft and Hard Conflict Constraints

open access: yesMathematics
For the classic 0–1 knapsack problem, there can be pairs of items that are in conflict. In other words, either at most one item can be inserted into the knapsack (hard conflict constraint) from the conflict pair or there may be a penalty (soft conflict ...
