This paper presents compact roundtrip routing schemes with local tables of size ˜O( √ n) and stretch 6 for any directed network with arbitrary edge weights; and with local tabl...
We study the following problem. Given a weighted planar graph G, assign labels L(v) to vertices so that given L(u), L(v) and L(x) for x ∈ X for any X ⊂ V (G), compute the dist...
