WebDec 29, 2024 · I never heard of any algorithm with the constraint of having an overlap between communities larger than a given threshold (4 here).. But I suggest the following: turn your graph into its line graph, use a classical node partitioning method that gives a hierarchy of communities, and then choose a partition that fits your requirements. More … WebApr 3, 2015 · I have tried using METIS to divided the matrix into subdomains, but METIS can only produce subdomains with nearly equal size. For the web link graph, it usually has blocks with different sizes because the domain or host of pages has different sizes. So, i want to find a method to divide the graph to subdomain with different sizes adaptively. porsche 911 pr
