After I 'run' this with dat file, this error appears but I can't figure out why this error comes out. Is there anyone who knows about this error? And cause this code is my first code in CPLEX SO plz give me any advice about this code. thx plz plz help me plz plz anyone help me plz plz ( the site wants me to add some more details...)
