On Dynamic Succinct Graph Representations

Miguel Coimbra, Alexandre Francisco, Luís Russo, Guillermo de Bernardo, Susana Ladra, and Gonzalo Navarro

We address the problem of representing dynamic graphs using k^2-trees. The k^2-tree data structure is one of the succinct data structures proposed for representing static graphs, and binary relations in general. It relies on compact representations of bit vectors. Hence, by relying on compact representations of dynamic bit vectors, we can also represent dynamic graphs. In this paper we follow instead the ideas by Munro et al., and we present an alternative implementation for representing dynamic graphs using k^2-trees. Our experimental results show that this new implementation is competitive in practice.
