IloCplex::UserCutCallbackI MIPCallbackI::getBestObjValue, MIPCallbackI::getCutoff, MIPCallbackI::getDirection, MIPCallbackI::getDirection, MIPCallbackI::getIncumbentObjValue, MIPCallbackI::getIncumbentValue, MIPCallbackI::getIncumbentValue, MIPCallbackI::getIncumbentValues, MIPCallbackI::getIncumbentValues, MIPCallbackI::getMyThreadNum, MIPCallbackI::getNcliques, MIPCallbackI::getNcovers, MIPCallbackI::getNdisjunctiveCuts, MIPCallbackI::getNflowCovers, MIPCallbackI::getNflowPaths, MIPCallbackI::getNfractionalCuts, MIPCallbackI::getNGUBcovers, MIPCallbackI::getNimpliedBounds, MIPCallbackI::getNiterations, MIPCallbackI::getNMIRs, MIPCallbackI::getNnodes, MIPCallbackI::getNremainingNodes, MIPCallbackI::getObjCoef, MIPCallbackI::getObjCoef, MIPCallbackI::getObjCoefs, MIPCallbackI::getObjCoefs, MIPCallbackI::getPriority, MIPCallbackI::getPriority, MIPCallbackI::getUserThreads, MIPCallbackI::hasIncumbent Description Inherited methods from IloCplex::CallbackI CallbackI::abort, CallbackI::duplicateCallback, CallbackI::getEnv, CallbackI::getModel, CallbackI::getNcols, CallbackI::getNQCs, CallbackI::getNrows, CallbackI::main Note:This is an advanced routine. Advanced routines typically demand a profound understanding of the algorithms used by ILOG CPLEX. Thus they incur a higher risk of incorrect behavior in your application, behavior that can be difficult to debug. Therefore, ILOG encourages you to consider carefully whether you can accomplish the same task by means of other Callable Library routines instead. An instance of the class IloCplex::UserCutCallbackI represents a user-written callback in an application that uses an instance of IloCplex to solve a MIP while generating user cuts to tighten the LP relaxation. IloCplex calls the user-written callback after solving each node LP exactly like IloCplex::CutCallbackI. It differs from IloCplex::CutCallbackI only in that constraints added in a UserCutCallbackI must be real cuts in the sense that omitting them does not affect the feasible region of the model under consideration.

IloCplex::VariableSelect IloCplex::VariableSelect Category Definition File Include Files Synopsis Description See Also Fields Inner Enumeration ilocplexi.h ilcplex/ilocplex.h VariableSelect{ MinInfeas, DefaultVarSel, MaxInfeas, Pseudo, Strong, PseudoReduced }; The enumeration IloCplex::VariableSelect lists values that the parameter IloCplex::VarSel can assume in IloCplex. Use these values with the method IloCplex::setParam(IloCplex::VarSel, value). See the reference manual ILOG CPLEX Parameters and the ILOG CPLEX User's Manual for more information about these parameters. Also see the user's manual for examples of their use.
