Cplex.NetworkCallback Members

Cplex.NetworkCallback overview

Public Instance Methods

Equals (inherited from Object) Determines whether the specified Object is equal to the current Object.
GetHashCode (inherited from Object) Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table.
GetType (inherited from Object) Gets the Type of the current instance.
Main (inherited from Callback) The method to be implemented by user callback classes.
ToString (inherited from Object) Returns a String that represents the current Object.

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.

Protected Instance Methods

Abort (inherited from Callback) Instructs CPLEX to stop the current optimization after the user-written callback finishes.
Finalize (inherited from Object) Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection.
IsFeasible Returns a Boolean value indicating whether the current solution is primal feasible at the moment the callback is called.
MemberwiseClone (inherited from Object) Creates a shallow copy of the current Object.

Protected Internal Instance Constructors
