Synthetically generated pb counting instances inspired by 3 different settings - auction (1000 instances), knapsack (1000 instances) and sensor placement in graph (1500 instances).

The auction and knapsack instances are all satisfiable (counts > 0) whereas the graph contains some small number of unsatisfiable instances (count = 0)

The OPB instances were converted to CNF using PBLib, in particular the pbencoder binary with default settings.
