An Improved Branch and Bound Algorithm for Location-routing Problems

open access: yes, 2009
An important limitation of the fixed charge location model,is the assumption that full truckload quantities are shipped from a facility to a customer.

DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

open access: yesAdvanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

A Simplicial Branch and Bound Duality-Bounds Algorithm to Linear Multiplicative Programming

open access: yesJournal of Applied Mathematics, 2013
A simplicial branch and bound duality-bounds algorithm is presented to globally solving the linear multiplicative programming (LMP). We firstly convert the problem (LMP) into an equivalent programming one by introducing p auxiliary variables.

Simulation‐Based Analysis of Insert Pull‐Out in Nickel‐Polyurethane Hybrid Foams Using CT‐Derived Geometries

open access: yesAdvanced Engineering Materials, EarlyView.
CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

Modal Analysis of Light Propagation, Polarization and Diffraction by Cholesteric Liquid Crystal Layers

open access: yesAdvanced Functional Materials, EarlyView.
The analysis of optical eigenmodes in chiral liquid crystal with perpendicular or tilted helical axis, and their correspondence with the external medium, leads to an intuitive understanding of the angle and wavelength dependency of transmissive and reflective diffraction.

DESIGN AND EXAMINATION OF ALGORITHMS FOR SOLVING THE KNAPSACK PROBLEM [PDF]

open access: yesAvtomobilʹnyj Transport (Harʹkov), 2015
The use of methods of branches and boundaries as well as the methods of dynamic programming at solving the problem of «knapsack» is grounded. The main concepts are expounded.

ON THE COMPUTATIONAL EFFICIENCY OF BRANCH-AND-BOUND ALGORITHMS

open access: yesJournal of the Operations Research Society of Japan, 1977
The behavior of the number of partial problems T(A) which are decomposed in a branch­ and-bound algorithm A (T(A) may be taken as a measure for the computational efficiency of A) is investigated in a fairly general setting. The first result is that the mean number f(n) of T(A) when A is applied to problems of size n grows at least as fast as ...

Autonomous Multi‐Objective Nanoscale Characterization of Combinatorial (Al, Sc, B)N Films Reveals Composition‐Dependent Ferroelectric Regimes

open access: yesAdvanced Functional Materials, EarlyView.
Autonomous scanning probe microscopy and multi‐objective Bayesian optimization navigate a ternary (Al,Sc,B)N combinatorial library. Registered photoluminescence, electron‐probe compositional mapping, and X‐ray diffraction connect local electromechanical function to defect‐sensitive emission, composition, and crystal structure.

Branch-and-bound algorithm to minimize the total completion time on two dedicated processors

open access: yesOperations Research Perspectives
In this paper, we propose an exact method for solving the problem of scheduling multiprocessor tasks on two dedicated processors with release dates. In this problem, we have three subsets of tasks, where these tasks need one or two dedicated processors ...
