Inverse Generalized Maximum Flow Problems

open access: yesMathematics, 2019
A natural extension of maximum flow problems is called the generalized maximum flow problem taking into account the gain and loss factors for arcs. This paper investigates an inverse problem corresponding to this problem. It is to increase arc capacities

Maximum Entropy Method for Solving the Turbulent Channel Flow Problem

open access: yesEntropy, 2019
There are two components in this work that allow for solutions of the turbulent channel flow problem: One is the Galilean-transformed Navier-Stokes equation which gives a theoretical expression for the Reynolds stress (u′v′); and the second ...

Efficient Algorithms on Multicommodity Flow over Time Problems with Partial Lane Reversals

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2020
The multicommodity flow problem arises when several different commodities are transshipped from specific supply nodes to the corresponding demand nodes through the arcs of an underlying capacity network.

A computational evaluation of constructive heuristics for the parallel blocking flow shop problem with sequence-dependent setup times [PDF]

open access: yes, 2021
This paper deals with the problem of scheduling jobs in a parallel flow shop environment without buffers between machines and with sequence-dependent setup times in order to minimize the maximum completion time of jobs.

Optimal Decision-Making Dealing with Enemy Sabotages Using the Maximum Flow Interdiction Problem in Multi-Period Dynamic Networks in Fuzzy Conditions [PDF]

open access: yesآینده‌پژوهی دفاعی, 2022
For a long time, one of the most important problems in wars has been the enemy's operations to destroy facilities and communication networks. The destruction of bridges and roads, air, missile, or artillery attacks, and the countless cyber-attacks in ...

Improved Time Bounds for the Maximum Flow Problem [PDF]

open access: yesSIAM Journal on Computing, 1989
Summary: Recently, \textit{A. V. Goldberg} [A new max-flow algorithm, Tech. Rep. MIT/LCS/TM-291, Lab. Comput. Sci., Mass. Inst. Technol. (Cambridge/MA 1985)] proposed a new approach to the maximum network flow problem. The approach yields a very simple algorithm running in \(O(n^ 3)\) time on n- vertex networks.
