We formulate two SMCF variants to minimize the cost of arc flows, while respectively restricting the Value-at-Risk (VaR) and Conditional Value-at-Risk (CVaR) of random path flow losses due to uncertain arc failure (reflected as network topological changes). We formulate a linear program to ...
In this paper we discuss the parallel asynchronous implementation of the classical primaldual method for solving the linear minimum cost network flow problem. Multiple augmentations and price rises are simultaneously attempted starting from several nodes with possibly outdated price and flow information. ...
problem. Conservation of flow through each node is assumed. Due to its special mathematical structure, this problem has a solution in integer flows, given that the data that define the network are integers. It is a linear-programming problem whose major constraints form a node-arc incidence ...
