Constraints exist between tasks and their children, and between sibling tasks; in addition, a limited number of "landmark" tasks is added which are exempt from this restriction. Branching factor 4–7; tree height 3–7; landmark ratio in [0,0.5]; probably of sibling edge in [0,0.5]. The weights of the constraint arcs are set such that at least one solution exists (i.e. the graph contains no negative cycles and the STN is consistent). This archive contains 121 graphs on 500–625 nodes, 748–1515 arcs, upper bound on treewidth 2–144.
