Cplex.Goal Properties

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

Public Instance Properties

BestObjValue Gets a bound on the optimal solution value of the active problem. When a model has been solved to optimality, this value matches the optimal solution value. Before optimality has been proven, this value is computed for a minimization (maximization) problem as the minimum (maximum) objective function value of all remaining unexplored nodes.
Cutoff Gets the cutoff for the objective value when nodes are being solved during branch-and-cut search. This value is typically computed from the objective value of an incumbent solution and the optimality gap. In the case of a minimization problem, for example, if the objective value of a node exceeds the cutoff value, the node can be pruned without the need to solve the node to optimality.
IncumbentObjValue Gets the objective value of the current best integer solution. This property queries the objective value for the current incumbent solution (that is, the best integer solution found so far). It cannot be set.
Nnodes Gets the number of nodes processed so far in the active branch-and-cut search.
NremainingNodes Gets the number of nodes remaining to be processed, or, equivalently, the number of active nodes in the tree.

Protected Instance Properties

Nbranches Gets the fraction of completion of the fractional cut generation. The returned values are in the range of 0.0 to 1.0.
Ncliques Gets the number of clique cuts that have been added to the model during the current optimization. problem.
Ncovers Gets the number of cover cuts that have been added to the model during the current optimization. problem.
NdisjunctiveCuts Gets the number of disjunctive cuts that have been added to the model during the current optimization. problem.
NflowCovers Gets the number of flow cover cuts that have been added to the model during the current optimization. problem.
NflowPaths Gets the number of flow path cuts that have been added to the model during the current optimization. problem.
NfractionalCuts Gets the number of fractional cuts that have been added to the model during the current optimization. problem.
NGUBcovers Gets the number of GUB cover cuts that have been added to the model during the current optimization. problem.
NimpliedBounds Gets the number of implied bound cuts that have been added to the model during the current optimization. problem.
Niterations Gets the number of iterations performed so far.
NMIRs Gets the number of MIR cuts that have been added to the model during the current optimization. problem.
ObjValue Gets the objective function value of the solution of the continuous relaxation of the current model during the current optimization.
