Protected Instance Properties

BestObjValue (inherited from MIPCallback) 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 (inherited from MIPCallback) 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 (inherited from MIPCallback) Gets the objective value of the current best integer solution. This method returns the objective value for the current incumbent solution (that is, the best integer solution found so far).
Model (inherited from Callback) Gets the model being solved when the invoking callback is called, i.E. the active model.
MyThreadNum (inherited from MIPCallback) 
Ncliques (inherited from MIPCallback) Gets the number of clique cuts that have been added to the node problem.
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.
Ncovers (inherited from MIPCallback) Gets the number of cover cuts that have been added to the node problem.
NdisjunctiveCuts (inherited from MIPCallback) Gets the number of disjunctive cuts that have been added to the node problem.
NflowCovers (inherited from MIPCallback) Gets the number of flow cover cuts that have been added to the node problem.
NflowPaths (inherited from MIPCallback) Gets the number of flow path cuts that have been added to the node problem.
NfractionalCuts (inherited from MIPCallback) Gets the number of fractional cuts that have been added to the node problem.
NGUBcovers (inherited from MIPCallback) Gets the number of GUB cover cuts that have been added to the node problem.
NimpliedBounds (inherited from MIPCallback) Gets the number of implied bound cuts that have been added to the node problem.
Niterations (inherited from MIPCallback) Gets the total number of iterations for solving node problems during the current optimization.
NMIRs (inherited from MIPCallback) Gets the number of MIR cuts that have been added to the node problem.
Nnodes (inherited from MIPCallback) Gets the number of nodes processed so far in the active branch-and-cut search.
NodeData Gets the user object attached to the current node. User objects can be attached to a node when the node is created with the method Cplex.BranchCallback.MakeBranch in a branch callback.
NremainingNodes (inherited from MIPCallback) Gets the number of nodes remaining to be processed, or, equivalently, the number of active nodes in the tree.
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 objective value of the potential incumbent.
UserThreads (inherited from MIPCallback)
