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. |
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. |
