**Table 1** **parameters** parameter description
Parameter	Mandatory	Description	Type	Value Range	Default Value
convergence	No	Convergence	Double	A real number between 0 and 1 (excluding 0 and 1)	0.00001
max_iterations	No	Maximum iterations	Integer	1 to 2000	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
