Questions about the results of multi-layer network aggregated

[johnqoe]

Hi KatolaZ!
Thanks for your really great work!
When I use the test data from the sample_data folder, the results of the global quality function and the aggregated networks as follows:
0.155614793291 -> [[0], [1], [2], [3]]
0.176459012214 -> [[1], [2], [0, 3]]
0.235974755926 -> [[1], [2, 0, 3]]
0.0 -> [[1, 2, 0, 3]]

as shown above，In the last step, what does the value of the global quality function equal to 0 mean? Does Network 1 need to be merged with 0, 2, and 3?

could you give some guidance? Looking forward to your reply？
