A blocker for F is a set of edges, of smallest possible size, that has an edge in common with every element of F. In [C. Keller and M. A. Perles, Blockers for simple Hamiltonian paths in convex geometric graphs of even order, Disc. Comput. Geom., 60(1) (2018), pp. 1-8] we gave an explicit description of all blockers for the family of simple (i.e., non-crossing) Hamiltonian paths (SHPs) in G in the `even' case |V(G)|=2m. It turned out that all the blockers are simple caterpillar trees of a certain class.
