Cplex.BarrierCallback Properties

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

Protected Instance Properties

DualInfeasibility (inherited from ContinuousCallback) A measure for the dual infeasibility of the current solution. If the current solution is dual feasible, this value will be 0. Otherwise it will be a positive value.
DualObjValue The current dual objective value.
Infeasibility (inherited from ContinuousCallback) A measure for the primal infeasibility of the current solution. If the current solution is primal feasible, this value will be 0. Otherwise it will be a positive value.
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 (inherited from ContinuousCallback) The number of iterations performed so far.
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 (inherited from ContinuousCallback) The current objective value. The current objective value is the objective value at the point when the callback is called. In the 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 or dual feasibility. In the barrier method, where the objective functions can be computed using dual or primal vectors and both definitions are not equivalent (unless optimality is achieved), the primal objective function is returned.
