Journal of Applied Sciences and Environmental Management, 2018 In an urban transport system, a dysfunction often occurred as demand for transportation infrastructure exceeds available supply. The result includes traffic congestion, higher travel time and cost, higher emission of harmful gases and general reduction ...

A note on efficient minimum cost adjustment sets in causal graphical models
Journal of Causal Inference, 2022 We study the selection of adjustment sets for estimating the interventional mean under an individualized treatment rule. We assume a non-parametric causal graphical model with, possibly, hidden variables and at least one adjustment set composed of ...

Maximum Flow and Minimum-Cost Flow in Almost-Linear Time
2022 IEEE 63rd Annual Symposium on Foundations of Computer Science (FOCS), 2022 We present an algorithm that computes exact maximum flows and minimum-cost flows on directed graphs with m edges and polynomially bounded integral demands, costs, and capacities in \(m^{1+o(1)}\) time. Our algorithm builds the flow through a sequence of

Minimum cost network flows: Problems, algorithms, and software [PDF]
Yugoslav Journal of Operations Research, 2013 We present a wide range of problems concerning minimum cost network flows, and give an overview of the classic linear single-commodity Minimum Cost Network Flow Problem (MCNFP) and some other closely related problems, either tractable or intractable ...

Faster Sparse Minimum Cost Flow by Electrical Flow Localization [PDF]
2021 IEEE 62nd Annual Symposium on Foundations of Computer Science (FOCS), 2022 We give an $\widetilde{O}({m^{3/2 - 1/762} \log (U+W))}$ time algorithm for minimum cost flow with capacities bounded by $U$ and costs bounded by $W$. For sparse graphs with general capacities, this is the first algorithm to improve over the $\widetilde{O}({m^{3/2} \log^{O(1)} (U+W)})$ running time obtained by an appropriate instantiation of an ...

Mean-Standard Deviation Model for Minimum Cost Flow Problem
, 2022 We study the mean-standard deviation minimum cost flow (MSDMCF) problem, where the objective is minimizing a linear combination of the mean and standard deviation of flow costs. Due to the nonlinearity and nonseparability of the objective, the problem is

Maximum flow and minimum-cost flow in multi-interface networks [PDF]
Proceedings of the 5th International Conference on Ubiquitous Information Management and Communication, 2011 In heterogeneous networks, devices can communicate by means of multiple wired or wireless interfaces. By switching among interfaces or by combining the available interfaces, each device might establish several connections. A connection is established when the devices at its endpoints share at least one active interface.

Traffic flow consideration in design of freight distribution system
IATSS Research, 2010 This study is part of a series of research projects on a distribution system we developed to deal with cases in a state-owned company. It concerns the design of the Public Service Obligation State-owned Company (PSO-SOC) distribution system.
