Routing with Forbidden Subgraphs

Andy Twigg (Univ. of Cambridge)

I will discuss computing distances and routing with forbidden subgraphs, in particular for planar graphs. In the model, one can label vertices of a graph G then must be able to answer distance queries for any G\X, where X is specified at query time by giving the labels for vertices in X. The aim is to minimize the label size and query time. In particular we show an interesting result, that the size bounds for computing stretch-1 distances around arbitrary subgraphs match those for simply computing d(u,v) for planar graphs.
