We study several network flow problems with the arc reversal capability and discuss their complexity. More specifically, we discuss the polynomial time algorithms for the maximum dynamic flow problem with arc reversal capability having a single source and a single sink, and for the maximum (static)...
Finally, the maximum flow problem with the minimum number of labels (MF-ML) problem is presented and discussed. The aim is to maximize the network flow as well as the homogeneity of the solution on a capacitated network with logic attributes. This problem finds a practical application, for ...
The Ford-Fulkerson algorithm is a simple algorithm to solve the maximum flow problem based on the idea of augmenting path. But its time complexity is high and it's a pseudo-polynomial time algorithm. In this paper, a parallel Ford-Fulkerson algorithm is given. The idea of this algorithm is...
We consider the maximum flow problem subject to the following assumptions. Assumption 1. The network is directed. Assumption 2. All capacities are nonnegative integers. This assumption is not necessary for some algorithms, but the algorithms whose complexity bounds involve Uassume the integrality of ...
Maximu m Flow Problem Assuming –source produces the material at a steady rate –sink consumes the material at a steady rate What is the maximum net flow from s to t? Ford-Fulkerson Algorithm Start with zero flow Repeat until convergence: –Find an augmenting path, from s to t along whic...
the congestion avoidance mechanism for real-time applications. After it is admitted, a real-time flow such as voice must be carried; if there are insufficient bandwidth resources to carry the flow within the delay and loss bounds of the application, the flow must be rejected or redirected befor...
Therefore, the pseudoflow-simplex algorithm is the fastest simplex algorithm known for the parametric maximum-flow problem. The pseudoflow algorithm is also shown to solve the maximum-flow problem on s, t-tree networks in linear time, where s, t-tree networks are formed by joining a forest ...
They found this structure was favorable to reduce charge recombination and enhance mass flow control of tri-iodide when used in the ionic liquid electrolyte. Therefore, it reached a maximum solar energy conversion efficiency of 4.9% with the C101 dye and a 7-μm-thick NW film. Roh et al. ...
IV.MAXIMUM FLOW TEST GENERATORS Finding maximum,ow is a well-studied problem, so the problem of ,nding a hard test for a particular maximum ,ow algorithm was studied for a long time as well. In this section several test generation algorithms known from the literature [6]–[8] are outline...
We show that classic PRE is also a maximum flow problem, thereby revealing the missing link between classic and speculative PRE, and more importantly, establishing a common high-level conceptual basis for this important compiler optimisation. To demonstr
