Now, I insert each combination into a table. If a combination isn't possible, the value ist "-1". All possible combinations get positive values ("0.02","0.04", etc.).Because of that I have to insert a special rule in model: "s.t. positive_result {i in I, j in J}: varcost[i,j] * x[i,j] >= 0;" Is there a easier way to insert only possible combinations into a table and to drop the special rule.
A linear table with generic entry i, j, x[i,k] That is roughly how GLPK's API fills the constraint matrix. -- Michael [email protected] "Pessimist: The glass is half empty.
