Dear all, I want to create a graph in C, and import a .txt file as following: ============= 0 49389 5 0 49390 3 1 49298 3 1 49391 5 2 49392 2 3 49393 5 ..... ============= It means an edge weighted 5 form 0 to 49389, an edge weighted 3 form 0 to 49390......(actually,it's fine that it's undirected). The graph is a little big, 200,000 nodes.(perhaps a sparse matrix)
Solution 1. save as a igraph_matrix_t, but it needs too many RAM. It's impossible Solution 2. use igraph_read_graph_edgelist, but it can't be weighted. The file only can be 2 nodes separated by a space. How can I create the graph from this big weighted edgelist file? Thanks for answering James Fu _______________________________________________ igraph-help mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/igraph-help
