WebModularity maximization One approach to finding such a partition is to define a function that quantifies the quality of a set of partitions, and then adjust the partition to maximize the quality. One popular quality measure is called modularity. WebFeb 1, 2024 · We are now ready to present our column generation algorithm for the modularity density maximization problem. To make the RDP have an optimal solution (i.e., bounded), we have to set an initial S ′ in the RDP appropriately.
