 '''I also have another question. '''

 In TSPLIB format there are two options: EDGE_DATA_FORMAT and
 EDGE_DATA_SECTION. Both of them are important because with them you can
 indicate what edges are real. I mean, a full matrix should indicates if
 some edges are unexistant (using either 0 or -1).

 So, using SYMPHONY..
 how can I indicate (in a FULLY MATRIX) if there's no edge between two
 vertices?
 (my EDGE_DATA_FORMAT and EDGE_DATA_SECTION flags are ignored.)
