Louvain (2.2.1)

**Table 1** parameters parameter description
Parameter	Mandatory	Description	Type	Value Range	Default Value
convergence	No	Convergence	Double	The value is a real number between 0 and 1.	0.00001
max_iterations	No	Maximum iterations	Integer	An integer ranging from 1 to 2147483647. For frontend calls, the range is [1, 2000]. The default value is 100.	100
weight	No	Weight of an edge	String	Empty or null character string Empty: The default weight and distance of edges are 1. Character string: The property of the corresponding edge is the weight. If the edge does not have a property, the weight is 1 by default. NOTE: The weight of an edge must be greater than 0.	weight
