A problem becoming more and more important is that of data dependency: the performance of an algorithm often highly depends on the input. Yet, for a given input, it is highly non-trivial to select the best solving strategy. In this work, we introduce a new methodology for evaluating speed...
An algorithm based on random Dijkstra algorithm and applying genetic algorithm to solve SPDRGS(Shortest Path problem on Dynamic Route Guidance System) was proposed. By applying random Dijkstra algorithm, the algorithm cleared out the biggest obstruction between the genetic algorithm and SPDRGS, which ...
This document describes a common problem with Open Shortest Path First (OSPF) in which the routes that are in the database do not appear in the Routing Information Base (RIB) or routing table. In most cases OSPF finds a discrepancy in the database so it does not install the route in th...
If the shortest path exists, then the reservation matrix is updated by subtracting one from each element along that path and route returns with this path; else, route returns unsuccessfully. After each successful route, PhaseAssign forms a new shiftgroup data structure (Fig. 13). This data ...
Clearly, the shortest path may be too expensive to be used. Nevertheless the decision-maker must be able to choose some solution, possibly not the best for all the criteria. In this paper we present two algorithms for this problem. One of them is an immediate generalization of the multiple...
The new method appears to be more efficient than alternative approaches to the problem through linear or dynamic programming. Some applications of the technique to scheduling and other problems are briefly described. 展开 关键词: CiteSeerX citations Finding the shortest route between two points in a...
To address the k shortest paths (KSP) problem, an intelligent optimization approach based on Genetic Algorithm (GA) is presented in this paper. A simple and intuitive natural path representation is firstly employed to be the chromosome encoding scheme. Then genetic operators specific to this encodin...
