Graph Theory for Metro Traffic Modelling [PDF]

2021 International Joint Conference on Neural Networks (IJCNN), 2021
A unifying graph theoretic framework for the modelling of metro transportation networks is proposed. This is achieved by first introducing a basic graph framework for the modelling of the London underground system from a diffusion law point of view.

Graph models for evaluating production capacities of enterprises [PDF]

Journal of New Economy, 2021
The known methods for evaluating production capacities of industrial enterprises mostly submit approximate estimates and are typical of the planned economy. Currently, their practical application is limited, because the product range of companies is no

On Decision-Making Algorithms in Discrete Optimization Problems

Современные информационные технологии и IT-образование, 2023
The article provides a comparative analysis of the efficiency of using several predictor functions, i.e. special auxiliary functions a priori evaluating the feasibility of choosing a separating element for a certain iterative algorithm. Cases of one, two

A Game for Learning How to Model in Graph Theory

Mathematics, 2022
In this article, we show how to introduce students to modeling while exposing the power of graph theory as a modeling tool. For that purpose, we propose a problem aimed at university students based on a game where the objective is to strengthen the learning of reachability and the shortest path algorithms.

On a graph model for reflectometry issues and some algorithms for their solution. Part 2. An approach to software implementation

Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2022
Backgrond. The relevance of the subject area under consideration is primarily due to the need to minimize the cost of so-called reflectometers, with the existing restriction on the condition of total monitoring of fiber-optic cables.

Part-scale thermal simulation of laser powder bed fusion using graph theory: Effect of thermal history on porosity, microstructure evolution, and recoater crash

Materials & Design, 2021
Flaw formation in laser powder bed fusion (LPBF) is influenced by the spatiotemporal temperature distribution – thermal history – of the part during the process.

On Computation Degree-Based Topological Descriptors for Planar Octahedron Networks

Journal of Mathematics, 2021
A molecular graph is used to represent a chemical molecule in chemical graph theory, which is a branch of graph theory. A graph is considered to be linked if there is at least one link between its vertices.
