Stable Flows over Time [PDF]

open access: yesAlgorithms, 2013
In this paper, the notion of stability is extended to network flows over time. As a useful device in our proofs, we present an elegant preflow-push variant of the Gale-Shapley algorithm that operates directly on the given network and computes stable ...

Graph orientation and flows over time [PDF]

open access: yesNetworks, 2014
Flows over time are used to model many real‐world logistic and routing problems. The networks underlying such problems—streets, tracks, etc.—are inherently undirected and directions are only imposed on them to reduce the danger of colliding vehicles and similar problems.

On the Price of Anarchy for flows over time [PDF]

open access: yesProceedings of the 2019 ACM Conference on Economics and Computation, 2019
Dynamic network flows, or network flows over time, constitute an important model for real-world situations in which steady states are unusual, such as urban traffic and the internet. These applications immediately raise the issue of analyzing dynamic network flows from a game-theoretic perspective.

Algorithms for flows over time with scheduling costs [PDF]

open access: yesMathematical Programming, 2020
AbstractFlows over time have received substantial attention from both an optimization and (more recently) a game-theoretic perspective. In this model, each arc has an associated delay for traversing the arc, and a bound on the rate of flow entering the arc; flows are time-varying.

Data for the ins and outs of involuntary part-time employment

open access: yesData in Brief, 2021
Data are US monthly time series of involuntary part-time employment stocks and flows from 1976 until 2019 (covering five economic downturns), derived from the US Current Population Survey (CPS).

A comparative analysis of the time-dependent magnetized blood-based nanofluids flows over a stretching cylinder

open access: yesHeliyon, 2023
This article explores the analysis of magnetized blood-based nanofluids flows over an extending cylinder. The nanofluid contains copper, copper oxide and iron oxide nanoparticles which are mixed with blood.

Minimum-Cost Flows Over Time

open access: yesCoRR, 2022
In this paper we show that every maximum minimum-cost flow over time problem has an optimal solution with a repeated structure if the given time horizon is large enough.

Convergence of a Packet Routing Model to Flows over Time [PDF]

open access: yesMathematics of Operations Research, 2021
Mathematical approaches for modeling dynamic traffic can be roughly divided into two categories: discrete packet routing models and continuous flow over time models. Despite very vital research activities on models in both categories, their connection was poorly understood so far.

Flows over Time with Load-Dependent Transit Times [PDF]

open access: yesSIAM Journal on Optimization, 2005
Flow variation over time is an important feature in network flow problems arising in various applications such as road or air traffic control, production systems, communication networks (e.g., the Internet), and financial flows. Another crucial phenomenon in many of those applications is that the time taken to traverse an edge varies with the current ...
