Solver offers predefined means of controlling its overall behavior. These means are known as global modifiers because they modify globally the behavior you can expect from Solver in your application. You can use global modifiers only in the member function IloSolver::solve.

• One category of global modifiers includes the search limits:
  • IloSolver::setFailLimit
  • IloSolver::setOrLimit
  • IloSolver::setTimeLimit

  Those member functions are implemented by search objects. These search objects can be used with goals:

  • IloFailLimit
  • IloOrLimit
  • IloTimeLimit
• Another category of global modifiers includes the objective minimization step:
  • IloSolver::setOptimizationStep
  • The last parameter of the function IloMinimizeVar
