Distance Oracles for Interval Graphs via Breadth-First Rank/Select in Succinct Trees
Meng He, J. Ian Munro, Yakov Nekrich +2
We present the first succinct distance oracles for (unweighted) interval graphs and related classes of graphs, using a novel succinct data structure for ordinal trees that supports…
