Dear all,

I have a directed graph G with 10,000 nodes. I am interested in identifying (l,r)-cores of G where l and r denote the in-degree and the out-degree of G, respectively. Mathematica has already developed separately:

KCoreComponents[G,k]

KCoreComponents[G, 3, "In"]

for in-degree for k=3

KCoreComponents[G, 3, "Out"]

for out-degree for k=3

The above codes separately finds the in and out-degrees. I am interested in finding SIMULTANEOUSLY the (l,r)-cores of G. Any idea about developing a code for this simultaneous determination of the cores?

Thanks. Temel
