چکیده
We extend the discrete-time dynamic ow algorithms presented in the literature to solve the analogous continuous-time dynamic ow problems. These problems include nding maximum dynamic ows, quickest ows, universally maximum dynamic ows, lexicographically maximum dynamic ows, dynamic transshipments, and quickest transshipments in networks with capacities and transit times on the edges.

Multi-layer Clustering Topology Design in Densely Deployed Wireless Sensor Network using Evolutionary Algorithms
Due to the resource constraint and dynamic parameters, reducing energy consumption became the most important issues of wireless sensor networks topology design. All proposed hierarchy methods cluster a WSN in different cluster layers in one step of evolutionary algorithm usage with complicated parameters which may lead to reducing efficiency and performance. In fact, in WSNs topology, increasin...
متن کاملOptimizing the Static and Dynamic Scheduling problem of Automated Guided Vehicles in Container Terminals
The Minimum Cost Flow (MCF) problem is a well-known problem in the area of network optimisation. To tackle this problem, Network Simplex Algorithm (NSA) is the fastest solution method. NSA has three extensions, namely Network Simplex plus Algorithm (NSA+), Dynamic Network Simplex Algorithm (DNSA) and Dynamic Network Simplex plus Algorithm (DNSA+). The objectives of the research reported in this...

متن کاملEfficient Maximum Flow Maintenance on Dynamic Networks
While many efficient algorithms for the maximum flow problem have been proposed over the years, they are designed to work with static networks, and thus they need to recompute a new solution from scratch every time an update occurs. Such approaches are impractical in many current application where updates are frequent. To overcome these limitations, this paper proposes efficient incremental alg...
متن کاملInverse Maximum Dynamic Flow Problem under the Sum-Type Weighted Hamming Distance
Inverse maximum flow (IMDF), is among the most important problems in the field ofdynamic network flow, which has been considered the Euclidean norms measure in previousresearches. However, recent studies have mainly focused on the inverse problems under theHamming distance measure due to their practical and important applications. In this paper,we studies a general approach for handling the inv...
