On Local Fixing

Part of the Lecture Notes in Computer Science book series (LNCS, volume 8304)


In this paper we look at the difficulty of fixing solutions of classic network problems. We study local changes in graphs (edge resp. node insertion resp. deletion), and network problems (e.g. maximal independent set, minimum vertex cover, spanning trees, shortest paths). A change/problem combination is locally fixable if an existing solution of a problem can be fixed in constant time in case of a local change in the graph. We analyze a variety of well-studied classic network problems with different characteristics.
