Lecture XIV MINIMUM COST PATHS

چکیده
Several problems which we studied under “pure graph problems” in Chapter (???) will now be generalized. Connectivity becomes considerably more interesting when we introduce cost functions. Connectivity has to do with paths. In the presence of cost functions, these paths has associated costs. We now study various problems related to paths of minimum cost. It is interesting to note that shortest algorithms can take advantage of the special nature of the input cost function in the following cases:

A Metaheuristic Algorithm for the Minimum Routing Cost Spanning Tree Problem
The routing cost of a spanning tree in a weighted and connected graph is defined as the total length of paths between all pairs of vertices. The objective of the minimum routing cost spanning tree problem is to find a spanning tree such that its routing cost is minimum. This is an NP-Hard problem that we present a GRASP with path-relinking metaheuristic algorithm for it. GRASP is a multi-start ...

Shortest Paths: Today we consider the problem of computing shortest paths in a directed graph. We are given a digraph G = (V,E) and a source vertex s ∈ V , and we want to compute the shortest path from s to every other vertex in G. This is called the single source shortest path problem. The algorithms we will present work for undirected graphs as well, by simply assuming that each undirected ed...
متن کاملProceedings of the Workshop on the Reuse of Web - based Information
A search engine can index a concept that appears entirely on a single page. But concepts can span several pages. For instance, a page on trees may be linked to a page on lecture notes for a data structures course. If the trees page does not specifically mention lecture notes, then a search engine search for lecture notes on trees will, at best, only partially match each page. In this paper we d...
