For every graph H, there exists a real number cH such that every graph that does not contain a subdivision of H (as a subgraph) is conﬂict-free cH-choosable.4 Note that graphs satisfying Theorem 1.3 are sparse in the sense that the number of edges is at most a linear function of the number of vertices.

We describe some further results related to Dilworth’s theorem for posets (1950), and matching theory in bipartite graphs. In this way, one can obtain fast algorithms for determining when a network is tree-based and, if not, to calculate how ‘close’ to tree-based it is.
