        assertEquals(4, Iterables.size(som.getInputs()));

        assertEquals(1 /* the SOM "brain" itself */ + 4 /* inputs */, Iterators.size(graph.V()));

        som.addOutput(0, 0, 0);
        som.addOutput(1, 1, 1);

        assertEquals(1 /* the SOM "brain" itself */ + 4 /* inputs */ + 2 /* outputs */,
