posted on 15.03.2011, 00:00 by L.R.(Léon) Planken, Mathijs de Weerdt, R.P.J.(Roman) van der KrogtSTNs randomly generated from the SMT-LIB "diamonds" benchmark. The files from SMT-LIB are DTP instances. STNs were generated from these by randomly selecting a literal from each clause. For each STN thus generated, the graph structure was maintained while modifying the weights of the constraint arcs such that at least one solution exists (i.e. the graph contains no negative cycles and the STN is consistent). This archive contains 504 graphs on 51–379 nodes, 49–379 arcs, upper bound on treewidth 2.
