Load an example network and place an output constraint

nnet_file_name = "../../src/input_parsers/acas_example/ACASXU_run2a_1_1_tiny_2.nnet"
net = Marabou.read_nnet(nnet_file_name)
net.setLowerBound(net.outputVars[0][0], .5)

Solve the query with DNC mode turned on, which should return satisfying variable values

options = Marabou.createOptions(snc=True, verbosity=0, initialDivides=2);
vals, stats = net.solve(options=options)
assert len(vals) > 0
