Cplex.NetworkCallback Properties

The properties of the Cplex.NetworkCallback class are listed below. For a complete list of Cplex.NetworkCallback class members, see the Cplex.NetworkCallback Members topic.

Protected Instance Properties

Infeasibility Gets the primal infeasibility measure. If primal feasibility is obtained, the value 0 is returned. Otherwise, this method returns a positive value. Since the network optimizer sees only the embedded network part of the full model, a solution considered to be feasible for the network optimizer may not be so for the full model.
Model (inherited from Callback) Gets the model being solved when the invoking callback is called, i.E. the active model.
Ncols (inherited from Callback) Gets the number of columns of the matrix representation of the active model being solved when the invoking callback is called.
Niterations Gets the number of iterations performed by the network optimizer.
Nrows (inherited from Callback) Gets the number of rows of the matrix representation of the active model being solved when the invoking callback is called.
ObjValue Gets the current objective value. The current objective value is the objective value at the point when the callback is called. In the network simplex method, this objective value may not reflect the objective function defined for the model being solved, but an artificial phase 1 objective function used to achieve primal feasibility. Also, since the network optimizer sees only the embedded network part of the full model, the objective value may not reflect the objective function of the full model.
