Sorry to bother you again. Now I try to use some datasets(arenas-meta.edges) get online as A1 for your REGAL program. As I learned from your paper, the input for this program is a jointed matrix in the form as A = [A1,0;0,A2].
The adjacency matrix A1 is the true adj of the network we focus on, while the other matrix A2 is just generated by A2 = P * A1 *P' (P is randomly generated).
Now, I have constructed both the jointed adjacency matrix A and the true-alignment matrix P as input in your method. But my output result is really bad... I only got 0.02 for score top10.
I've spent 2 days on contructing the correct-format input file for the program. The input file I constructed and the corresponding code generating it have been upload as appendix.
I'm afraid it would be a bother for you to read my code or find mistakes in it... So would you like to give some more detail about how to construct the joint adj A and the truth alignment file P which respectively respond to the file named "arenas_combined_edges.txt" and the file named "arenas_edges-mapping-permutation" in your program? It would be better if you already have some program deal with this problem and if you can share it with me...
I have been confused on this problem for a long time... I'm looking forward to your reply.
