Get different result after upgrading to 0.10.1 #157

When I upgrade leidenalg from 0.8.10 to 0.10.1, I get a different result despite I use the same input data and same input parameters.

I used the parameters as below: partition_type = leidenalg.RBConfigurationVertexPartition n_iterations = -1 seed = 0 resolution_parameter = 1 weights were got from an igraph object created with Neighbors Connectivities which were calculated by input data, I have checked the both input weights are the same.

Could anybody tell me why or how to keep the result stable?

There were some changes between these two versions that affect the results of the clustering. For that reason, it is not possible to ensure the results remain identical. If you absolutely insist the results remain identical, you are forced to stick to the 0.8 series.

Got it, thanks for replying.
