To make the RDP have an optimal solution (i.e., bounded), we have to set an initial S ′ in the RDP appropriately. One trivial way is to use the singletons, i.e., S ′ = {{v} ∣ v ∈ V}.Note that the output of any algorithm for the modularity … greater than or equal to than sign https://connersmachinery.com
