Abstract The Graph Level Order Unary Degree Sequence (GLOUDS) is a new succinct data structure for directed graphs that are “tree-like,” in the sense that the number of “additional” edges (wrt a spanning tree) is not too high. The algorithmic idea is to represent a BFS-spanning tree of the graph (consisting of n nodes) with a well known succinct data structure for trees, named LOUDS, and enhance it with additional information that accounts for the non-tree edges. In practical tests, our data structure performs well for graphs containing up to m= 5 n edges, while still having competitive running times for listing adjacent nodes.
